Abstract

Recently, the advancement of multilevel inverters (MLI) has been a crucial factor in high power and medium voltage applications. This MLI has multiple topologies and has been used in a variety of applications. Cascaded MLI is preferred over other forms of multilevel inverter topologies. Nonetheless, significant obstacles are encountered when implementing these topologies. They necessitate an increased number of switches, DC sources, capacitors, and diodes. Increased losses and total harmonic distortion (THD) will be present in the system. In addition, the MLI is more expensive. The better construction of a multilevel inverter results in more output levels with fewer switches, sources, and driver circuits, as well as low THD. A new single-phase cascaded asymmetrical DC voltage sources based multilevel inverter design and the selective harmonic elimination (SHE) approach are used to attain these goals. After confirming in MATLAB/Simulink, the hardware implementation of the multilevel inverter in 21 levels was completed in this article.

Abstract

The application of hybrid energy power plants is one solution to save electricity cost in buildings of government agencies, industries, and universities. The problem with using hybrid power plants that use solar energy sources and paid electricity networks is that sunlight energy cannot produce energy consistently from sunrise to sunset. Maximum energy can only be obtained when the sun is vertically acceptable to the photovoltaic (PV). This results in electrical loads having to be disconnected or switched back to the grid. The application of an electrical power sharing system synchronization controller system (SCS) can automatically regulate the use of electrical energy to low PV energy. The results of research on the application of hybrid PV using the SCS system with a rooftop solar panel system at the Gorontalo State University Building can produce a total electrical power of 600,975 kWh. The need for electrical power from January to September 2022 amounted to 859,151 kWh. The SCS hybrid power plant can reduce the use of paid electrical energy and its costs by 83.60%. The investment, operational, and maintenance cost requirement is IDR 10,747,886,801. The return on investment (ROI) analysis results show that the return on investment can be achieved for up to 34 years.

Abstract

This paper explores the challenges associated with the control of a two-stage three-phase electrical grid connected to a photovoltaic (PV) system. The core control objectives encompass: i) Maximizing the utilization of available power from the PV panel; ii) Regulating the DC-link voltage to a predetermined reference; and iii) Ensuring power factor correction (PFC) on the grid side. To achieve these objectives, two loops nonlinear controller are developed. In the outer loop, the duty cycle of a boost converter is controlled using integral backstepping technique with the perturb & observe (P&O) algorithm, which provides reference voltages to track maximum power points, and Lyapunov theory to ensure the system’s stability. In addition, the Inner loop is designed using proportional integrator (PI) controller to ensure the unit power factor correction. An assessment of the proposed method is conducted through a comparative study with the backstepping technique, demonstrating the effectiveness of the suggested solution. The results have been validated by numerical simulation within MATLAB/Simulink power systems environment.

Abstract

Across various applications, electrical machines are intensely replacing conventional hydraulic and pneumatic actuators in applications with a higher degree of complexity. In our previous study, a SynRM machine with a segmented rotor was designed to operate as a clutch actuator, to be placed in the gear housing which suffers from a high ambient temperature. This makes it necessary to predict the considerable potential influence of temperatures. This study evaluates the influence of winding resistance variation due to temperature on the machine power factor and its operating area. The evaluation is done for the condition of the automotive battery supply of 14 V, 50 A. An experimentally validated analytical model based on the SynRM machine phasor diagram was used to assess the torque-speed area and power factor variation. The main contribution is presented in the form of a tool represented as an abacus that allows the user of the machine to track the power factor and maximum speed for a range of winding resistance values. On a selected operating point of (Γ, N) = (0.57 N.m, 3500 rpm), it is demonstrated that the winding resistance should be reduced below 0.2 Ω, to be able to achieve the targeted speed, while the power factor is at 0.9.

Abstract

The multilevel inverters are considered as the efficient power converters. Because of the predominant properties of multilevel inverters over the two-level inverters, these are acquiring more popularity. The aim of research is to minimize the number of switches as well as sources. In this paper, total harmonic distortion (THD) analysis for different modulation indices is carried out for a 15-level inverter with fewer switches. This 15-level inverter uses three asymmetrical sources with nine switching devices. Nearest level control modulation technique provides the pulses for the switching devices at fundamental switching frequency. Evaluation of THD has been carried out in MATLAB/Simulink.

Abstract

Permanent magnet synchronous motor (PMSM) is widely used in different applications because of their different key operation features. But despite having important key features, PMSM suffers from torque ripple when simple control techniques like direct torque control (DTC) are employed. Several approaches have been raised by many researchers to lessen the ripple when DTC is used for controlling the PMSM drive. In this work, duty ratio-optimized DTC control, which has the same simplicity as conventional DTC (CDTC), and delay compensation for input signal prediction are proposed. In the proposed system, to determine the duty ratio, slope manipulation was made by considering the minimization of torque error and forcing the developed torque to be equal to the reference torque at the end of the span. An online slope determination approach was employed to compute the duty ratio. MATLAB 2021b is used for simulation purposes. The dynamics and steady-state performance of the proposed scheme were tested for both variable-load and variable-speed operations. In addition, the harmonic performance and ratio of harmonic power loss to total active power loss of the motor were evaluated. In general, the proposed scheme performs effectively in reducing steady-state ripple and harmonic.

Abstract

Information technology servers are complex, delicate, and expensive systems; power grid interruption is one of the possible causes that can lead to hardware damage or logical disk structure damage, with severe consequences. Moreover, a power grid drop causes a sudden interruption of the services managed by a server. Uninterruptible power supplies (UPS) provide backup power when the regular power grid source drops. UPSs can only maintain a server for a short time. Therefore, it is necessary to introduce a blackout manager who can correctly shut down the server activities. Moreover, the manager must be able to restore the servers' status when the electrical grid power returns to its normal state. This paper proposes a possible UPS power manager able to manage servers during a prolonged electrical blackout. The UPS power manager identifies the blackout and keeps the servers safe by saving their state and shutting them down properly. Following the power grid restoration, the UPS power manager restarts the servers and restores their state. The proposed approach has been evaluated on a virtualization cluster used for critical activities at the Politecnico di Torino.

Abstract

This article suggests installing a series compensator on grid-connected induction motors that allows for the ride-through of unbalanced voltage sag. Fuzzy logic controls the motor voltages in a standard three-phase voltage source inverter or voltage source inverter (VSI). An open-ended three-phase machine and the grid form a series connection for the VSI. The proposed system is well suited for uses where frequency variation is unnecessary, such as with large pumps or fans. There is no requirement for a direct current (DC) source or injection transformer when conducting an electric mutual coupling The severity of the sag in the grid voltage that will prevent EMC from shutting down is proportional to the load on the motors. An increase in the voltage of the DC link may be necessary if the voltage is not balanced. A 1.5 hp four-pole induction motor was used alongside grid voltage disturbances to test the proposed compensator's ride-through capability. Grid's current analysis demonstrates that the proposed system does not require the addition of a passive filter to achieve low levels of total harmonic distortion (THD). Additionally, the control strategy, component ratings, and analysis of the converter's output voltage operating principle and pulse width modulation technique are covered. The system's viability is shown via simulation and experimental results.

Abstract

In this paper, a switched capacitor cell buck converter, combining two-phase interleaved operation with gallium nitride or GaN-FET technology has been presented. These technologies make it suitable for wide range of applications where efficient power conversion is essential. To validate efficacy of the proposed converter with GaN-FET, its performance is examined in relation to a similar converter that utilizes metal-oxide semiconductor field-effect transistor (MOSFET) switches. The proposed converter offers a potential advantage over the DC-DC interleaved buck converter with MOSFET switches by allowing operation at higher frequencies, resulting in a smaller inductor value. The design parameters of the inductor have also been presented. The simulation results indicate that the converter exhibits better performance than MOSFET-based converter with regards to total power losses, input and output current ripple, output voltages and subsequently achieves higher efficiency at various duty cycles and different loads. Finally, experimental verification is done to validate the simulation results.
