Publisher : Institute of Advanced Engineering and Science

This paper presents the optimization design and a detailed implementation in FPGA (Field-Programmable Gate Array) of a power control strategy. This strategy is based on the phase shift angle of the inverter output voltage with respect to the grid voltage and DSPWM (Digital Sinusoidal Pulse Width Modulation) patterns “Phase shift angle-DSPWM” for an inverter for photovoltaic system connected to the grid. The proposed control can synchronize a sinusoidal inverter output current with a grid voltage and control the power injected into the grid. Detailed development of a digital controller with lower hardware and computation requirement is proposed. Description on the digital implementation of the A/D converter, the PI compensator, the phase shift and the DPWM, is provided. This digital control exhibit simplicity, reduction of the memory requirements and power calculation for the control. The functional structure of this system with digital control has been validated with simulations and experimental results.

Understanding the consumption patterns in a working space is important for evaluating the causes of energy wastage and for developing strategies towards specific energy reduction methods. The intent of metering systems in buildings is to provide adequate data that help improve building systems performance. The results of the analysis offer the potential to improve the energy efficiency of the building and reduce the operation costs. Researchers of Polytechnic University of Madrid and American University of Ras Al Khaimah have developed a metering and control system that processes and analyzes the digitalized signals. This system can collect, analyze and manage the electrical consumption in buildings. It is non-intrusive, can be easily deployed in electric boards and sends data to a central base station located away from the metering device. In this article the system is tested in an educational facility with a wide range of uses. The lighting fixtures, power outlets and HVAC devices are analyzed in offices, classrooms and architecture studios. This article concludes that energy audits for longer time periods help building managers understand device profiles, occupant behavior and environmental context.

With growing demand in renewable energy, solar photovoltaic (PV) technology is becoming more popular. A number of research has been carried out to increase the efficiency of the PV system. One of them is improving the Switch Mode Power Supplies (SMPS) performance to ensure maximum solar energy extraction. This paper looks at buck type SMPS suitability for use in solar PV installed in residential houses. The main issues that affect the response from the output are identified. The work will utilise the LT SPICE software to carry out the simulation. The primary objective of the study is to design an improved converter controller which is more robust and is able to maintain constant output. The emphasis is on good efficiency, stability and low output voltage ripple. This could be achieved by using the current mode control (CMC) techniques – an alternative design to the voltage mode control technique (VMC). Results obtained via simulations reveal strong evidence of CMC superiority over the VMC.

Publisher : Institute of Advanced Engineering and Science

In this paper, an experimental investigation of a three phase quasi Switched Boost Inverter (qSBI) topology is proposed and analysed with an improved Pulse Width Modulation strategy. The qSBI is capable of providing both boost and inversion actions in a single stage. The improved PWM control technique can provide a higher boost with the reduced duty ratio. The theoretical analysis presented in this work is validated using an experimental set up of 100W qSBI topology and hardware results are shown for verification. The improved PWM strategy is implemented and firing pulses are generated in FPGA SPARTAN 3E kit. With the duty ratio of 0.05, the peak ac load voltage of 80 V is obtained. The performance of three phase qSBI is analysed with both conventional PWM strategy and improved PWM strategy. The observations are presentated in detail.

Voltage regulation and phase quantity increase of two high-power 12-phase rectifiers Valery Safonov; Mikhail Dziuba
International Journal of Power Electronics and Drive Systems (IJPEDS) Vol 10, No 3: September 2019
Publisher : Institute of Advanced Engineering and Science

In this article, we present a new method of simultaneously increasing the phase quantity and regulating the rectified voltage for two 12-phase high-power rectifiers operating at a common load. Self-excited voltage inverters separately form the necessary voltages for voltage regulation and for increasing the phase quantity. The formed voltage is input with the help of a common booster transformer. Separating the inverters functions and using the common booster transformer makes it possible to reduce the installed power of the equipment significantly compared to similar circuits when the regulation range of the rectified voltage is up to 5%. Calculations show that the inverter power for increasing the phase quantity is about 3% of the rectifier power. The circuit was modeled in MatLab/Simulink and the electromagnetic processes in the rectifier were studied. The proposed method makes it possible to reduce the total harmonic distortion of the network current and the pulsation coefficient of the rectified voltage to the values typical for 24-phase rectifiers.

A new closed loop AC to DC ĈUK converter is presented in this paper. The conventional ĈUK AC to DC converter has no feedback circuit. Thereby, the output voltage of the converter changes while changing the load. The proposed closed loop converter can regulate voltage with the variation of load over a wide range. Moreover, the power factor and Total Harmonic Distortion (THD) of the supply side current found quite satisfactory from this closed loop ĈUK converter. The converter operates in four steps with a different combination of voltage polarities and switching states. The feedback path consists of a voltage control loop and a current control loop. The closed loop ĈUK converter in this study is compared with the open loop version. Additionally, the comparison is made with the conventional converter of the same topology. The effectiveness in terms of power factor and THD of the proposed converter is verified using simulation results.

In this paper, we propose a new power generating circuit for passive ultra high frequency (UHF) RFID tag. The proposed power generating circuit consists of a RF limiter, a high power efficiency and high sensitivity full wave radio frequency (RF) wave rectifier and a low-power regulator with NMOS diodes work like a DC-limiter. The design method proposed in this study use one low drop out (LDO) regulator to provide tow output stable supply voltages vdd1 of value 1V for the digital section supply, and vdd2 of value 0.5V for the analog front-end section power supply. The proposed power generating circuit is optimized in terms of power consumption of RFID tag system to have a high operating range under conditions of 50 Ohm antenna, -24 dBm input RF power, 900MHz and 1 M DC, with low power dissipation and 29.15% large power conversion efficiency. The power generating circuit was designed, simulated and layouted in Cadence using TSMC 180 nm technology. The final design occupies approximately 0.25mm2.

Electric bike (E-Bike) is a bicycle driven using an electric motor and uses batteries as the energy source. It is environmentally friendly as no exhaust gas is resulted during its operation. More than one battery is normally required, being arranged in series or in parallel connection. Over limit or overloaded conditions of battery usage will reduce the lifecycle of battery, speed up its replacement and add to the maintenance cost of electric bike. This paper proposes the prevention of such degrading condition using a tool to manage the battery usage both during the charging and discharging process. The proposed electronic Battery Management System (BMS) serves to regulate, monitor, and maintain the condition of batteries to prevent any possible damage. The resulted BMS design could provide a well balancing action in a battery system consisting of 13 cells utilizing the cell-to-cell active balancing method. The test results showed that the proposed BMS could monitor the individual cell voltage with an average error of 0.032 V (0.824%), while reading the charge and discharge current with an average error of 0.04 A (6.25%), and the battery pack temperature with an average error of 1.21oC (2.9%). Additionally, the BMS could offer a functional battery pack protection system from conditions such as undervoltage, overvoltage, overheat, and overcurrent.

With the growing interest in renewable energy resources, a various number of studies and development for photovoltaic (PV) systems have investigated to satisfy global needs in energy. The larger interest in PV resources has increased request for suitable apparatus with which to test PV systems. This paper deals with the design of an indoor PV source emulator using an actual PV panel to facilitate PV system testing under real environment conditions. A low-cost Arduino Mega256 microcontroller-based data acquisition system (DAQ) approach has been developed to collect the data in term of voltage, power and current based on different levels of light intensity and temperature as well as under partial shading conditions. Hence, the proposed system is not just a solar emulator but it’s a complete solar emulator-DAQ system that can emulate the sunlight and monitor the PV parameters and then collect and store the data for further research investigation. The proposed monitoring system provides real time update of the solar panel characteristics at any time in the year without relying on the weather changes. This data acquisition system will be of superior interest for undergraduate and graduate students as it is both open-source and ﬂexible. The details design of the proposed PV solar emulator and data logger and its implementation are described.

Nowadays the main goal of sustainable energy supply is the use of renewable energy sources and, in addition, the increased efficiency of the energy used. One possibility of using renewable energies is the use of solar energy through photovoltaic panels. Taking into account the meteorological characteristics of the country in which the study takes place, it appears that the use of photovoltaic panels will be available most of the time during the year. We applied a model of hybrid solar collectors for maintaining the cell temperature near 25°C by introducing a flat plate cover integrated with solar cells. This method represents a way to increase the efficiency of the solar collector. This will enable the production of electricity from the part of the photovoltaic panel incorporated into the solar collector, in which the water temperature will increase, and this heat from the water is due to the effect of sunlight and as a result of cooling the part of the photovoltaic panel. This represents an increase in the efficiency of the system and the main purpose of our analysis.
