This paper discussed the latest development of single-phase single stage current source inverters for grid connected photovoltaic system. In general, the single-phase single stage inverters are categorized into four types of topologies: 1) H-Bridge, 2) buck-boost, 3) flyback type chopper and 4) Z-Source inverter. The inverters are compared and evaluated on switching technique, switching frequency,...
This paper presents modeling and analysis of applying Single Phase Matrix Converter (SPMC) in a single phase Dynamic Voltage Restorer (DVR) topologies. A simulation was done using Matlab/Simulink software to model and analyze the DVR system embedded with SPMC towards mitigating the voltage sag. In this simulation a single line to ground fault is used to create the disturbance to the load and a Sinusoidal...
This paper illustrates the development of MATLAB/GUIDE (Graphical User Interface Development Environment) software program to simulate the performance of three phase induction machines complete with graphical analysis display on a computer. The selected simulation results used 1 horse power (hp) and 20 hp three phase induction machines. Analysis includes Transient response, Starting method: (a) Rotor...
This paper presents the operation of Single-Phase Matrix Converter (SPMC) that could synthesize a greater AC output voltage from a given AC supply voltage. Insulated Gate Bipolar Transistors (IGBTs) are used to implement the SPMC topology while the well-known Sinusoidal Pulse Width Modulation (SPWM) scheme is used as the switching technique to synthesize the output waveform. Simulation model was developed...
This paper is concerned on Xilinx FPGA design for SPWM control of Single-Phase Matrix Converter (SPMC). The Sinusoidal Pulse Width Modulation (SPWM) technique is used to synthesize the output voltage. The power circuit uses the Insulated Gate Bipolar Transistor (IGBT) as switching device in the SPMC implementation. Safe-commutation strategy was incorporated to solve switching transients. A Xilinx...
This paper proposes an implementation of a new safe-commutation strategy for controlled rectifier operation using single-phase matrix converter (SPMC). The Pulse Width Modulation (PWM) technique was used to calculate the switch duty ratio to synthesize the output. The proposed safe-commutation strategies were developed through an arrangement of commutation switches that allows dead time to avoid voltage...
