Abstract

Conventionally, only the standalone operation of a single-phase fault tolerant-based 5-level neutral point clamped (SPFT-5L-NPC) inverter with two stiff DC sources has been explained with consideration of phase disposition pulse width modulation (PD-PWM) technique. In this topology, the bidirectional switch arrangement consists of four diodes and one IGBT switch. This arrangement inherently increases conduction losses of topology. Generally, any NPC inverter topology suffers from a DC-link capacitor voltage (DCL-CV) balancing issue. In the conventional contribution of work, authors have not discussed the front-end voltage balancing issue. This study describes the extension work of a single-phase grid connection with a modified 5L-NPC (M5L-NPC) inverter topology, taking into account the aforementioned concerns. In this topology, the simple front-end chopper circuit has been utilized to balance the DCL-CVs and to reduce conduction losses, another arrangement of bidirectional switch has been utilized. In this paper, both standalone and grid connections of M5L-NPC topology have been explained along with control of DCL-CVs. The grid-connected important objectives of active power control (APC), reactive power control (RPC), and injecting sinusoidal current with low harmonic distortion have been discussed thoroughly considering a simple control strategy.

Abstract

High-voltage DC generation is essential for industrial, medical, and scientific applications, such as X-ray machines, particle accelerators, and electrostatic precipitators. Existing high-voltage DC generators face challenges such as high cost, complexity, and inefficiency. A simplified and cost-effective solution that can reliably generate high-voltage DC from a low DC power supply is needed. This paper discusses the design and implementation of a high-voltage DC generator with a low-voltage DC power supply input. The generator employs a push-pull inverter to transform the DC 12 V voltage into AC 400 V at a frequency of 20 kHz. A Cockcroft-Walton circuit, comprising a positive and a negative Cockcroft-Walton circuit, then steps up this voltage. The Arduino Nano microcontroller uses pulse width modulation (PWM) signals to control the system. This research aims to provide a reliable and economical high-voltage DC voltage generation system for various applications. We discuss the design process and hardware implementation in detail. We set the target output voltage of this hardware at 10 kV DC. MATLAB/Simulink simulation software verifies the performance of the proposed high-voltage generator, and hardware implementation validates its effectiveness. The proposed high-voltage DC generator's hardware tests successfully produced an output voltage of 14.12 kV DC.

Abstract

Despite the fact that temperature affects how much power is produced by solar panels, a temperature that exceeds a certain threshold results in a reduction in output. Additionally, there are losses when switching is controlled in inverters using different control approaches like pulse width modulation (PWM), sinusoidal pulse width modulation (SPWM), and multiple pulse width modulation (MPWM). The type of control method and temperature have an impact on these losses. Here, the MPWM approach is used to analyze it at various temperatures. A metal-oxide-semiconductor field-effect transistor or MOSFET-based and an insulated gate bipolar transistor (IGBT)-based inverter are also planned. Their switching losses at various temperatures are contrasted. For a range of temperature values, the IGBT-equipped inverter is discovered to be a low-loss inverter. Compared to an IGBT inverter, the MOSFET inverter has a comparatively higher loss.

Abstract

This paper aims to present and analyze the fractional order proportional-integral-derivative (FOPID) control technique of the DC-DC two-level boost converter. The state-space averaged (SSA) method is used to build a small-signal converter mathematical model, which is a crucial task for the control design. A FOPID controller based on the Nelder-Mead optimization algorithm and an artificial intelligence strategy based on a fuzzy logic controller (FLC) are both designed for the voltage mode control (VMC) approach and operate on the continuous conduction mode (CCM). Various step changes in the input voltage amplitude and output load are applied to analyze the performance of the proposed control techniques. In addition, detailed simulation results using the MATLAB-Simulink system are extensively discussed.

Abstract

Leakage current flow is an important issue of transformerless (TL) inverters due to the absence of galvanic isolation between the source and grid sides in grid-connected solar photovoltaic (PV) systems. This article proposes a five-level (5L) TL direct ground point (DGP) type inverter employing two switched capacitors (SCs). The DGP configuration shares a common ground point for the PV negative terminal with grid neutral, thereby completely suppressing the leakage current. The employed semiconductors endure maximum voltage stress equivalent to the input voltage, while the switched capacitors (SCs) are rated at only half of the input voltage. This significantly reduces both the size and cost of the inverter. In addition, it uses reduced power components and has a lower total standing voltage per unit among the recent same art of topologies. A detailed comparison to show the merits of the proposed inverter is presented. Simulations and experiments were conducted at a 1 kW output power level in stand-alone as well as grid-connected mode to validate the feasibility of the proposed inverter.

Abstract

As interest in alternative energy sources grows, grid-connected inverters are getting more advanced. Thus, to synchronize the output waveform of an inverter with the grid supply system, the frequency and phase angle ought to be consistent. This paper presents an enhanced digital implementation controller for a grid-connected inverter using the sinusoidal pulse-width modulation (SPWM) switching technique via an appropriately designed low-pass filter. The main contribution of the proposed digital controller algorithm is to synchronize with the grid for the next half-cycle. The proposed control technique used the integrated response from the zero-crossing detector (ZCD) circuit for every half-cycle to trigger the digital phase-locked loop (PLL) implemented using field-programmable gate array (FPGA). An experimental 100 W single-phase full-bridge inverter prototype tested and validated the proposed control algorithm to prove the switching approach works. From the experimental results, the proposed control algorithm demonstrates synchronization with the grid voltage within 8 ms during startup. Furthermore, it exhibits the ability to adapt to phase changes when subjected to a distorted grid, achieving synchronization within 42 ms. This research also emphasizes synchronization between the grid waveform and the inverter output via the phase angle difference.

Abstract

This paper presents the topology and machine learning-based intelligent control of a single-stage grid-connected high-power photovoltaic (PV) system for quality power export to the grid and optimal net energy utilization. A nineteen-level bi-modular inverter is proposed for efficient single-stage PV power conversion. The proposed integrated intelligent machine learning-based control serves for power conversion control as well as supervisory control for hourly PV energy estimation and load demand control for optimal energy consumption. The objectives of power control are extracting maximum power from PV sources and exporting power to the grid at unity power factor. While the objectives for supervisory control are local load demand control for exporting power at higher export prices. The proposed system is implemented using MATLAB/Simulink to validate the efficiency of power conversion, effectiveness of machine learning for energy estimation, and load relay control for optimal energy pricing. The results proved efficient tracking of maximum power, unity power factor at grid terminals, and load relay control for PV energy availability and export cost function.

Renewable energy sources from sunlight using 2×100 Wp photovoltaic (PV) modules as the main source in this study, as well as grid energy sources functioned as backup energy. This ATS uses inverter input rating methods and standard AC voltage drop/over, a novelty of this study. The amount of current during testing is up to 14.09 A. The value of the inverter input voltage affects the quality of the inverter output voltage, there is a stability of the inverter output voltage from the AC voltage standard ±5% of the, lowest voltage value of (Vo_inv) = 223.9 V and the highest value (Vo_inv) = 226.1 V, at the time of (Vi_inv) max = 14.15 V and (Vi_inv) min = 12.66 V. It can be concluded that the ATS works in the PV position of the supply to the e-bike load, in the PV state it can produce power of a maximum value of 135.9 W at 11:25 am and is at the lowest power of 31 W at 03:31 pm. This ATS device in the switch mode successfully implemented a duration range of 10-21 ms, during the transfer of energy.

Abstract

Forecasting solar photovoltaic power ensures a stable and dependable power grid. Given its dependence on stochastic weather conditions, predicting solar photovoltaic power accurately demands applying intelligent and sophisticated techniques capable of handling its inherent nonlinearity and volatility. Controlling electrical energy sources is an important strategy for reaching this energy balance because grid operators often have no control over use patterns. Accurately forecasting photovoltaic (PV) power generation from highly integrated solar plants to the grid is essential for grid stability. This study aims to improve forecasting accuracy and make accurate predictions of solar power output from the selected grid-connected PV system. In this study, the weather data was collected on-site and recorded PV power from a 20 kW on-grid system for one year, and different machine learning techniques like deep neural networks, random forests, and artificial neural networks were evaluated and benchmarked against reference support vector regression model. With improvements in forecasting accuracy of 2 to 37% over the reference model at study location (22.780 N, 73.650 E), College of Agricultural Engineering and Technology, Anand Agricultural University, Godhra, India, simulation results showed that the random forest technique is effective for the forecasting horizons of 1 to 4 hours.

Abstract

The surface-mounted permanent magnet synchronous motor (SPMSM) is one of the electric machines applied widely in the fields of electric vehicles (EVs) and electrical drives due to their good characteristics such as high power density, lower mass, high efficiency, and lower torque. For the SPMSM, there are two types of SPMSM, i.e., the inner rotor SPMSM and the outer rotor SPMSM. To analyze and compute advantages and disadvantages, as well as to compare the performances of these two motor types, this research proposes an analytical model to design preliminarily the main/required parameters of the SPMSM with inner and outer rotor types. Subsequently, a finite element method is developed to simulate, analyze, and compare the electromagnetic parameters of the proposed motors. Via the developed methods, the obtained results will also indicate the performances of both types of motors. In particular, it will provide a good recommendation for choosing the SPMSM with an inner or outer rotor structure for traction applications.
