In this project, the implementation of a single phase AC/AC converter will be discussed. An IGBT single phase converter is built using MATLAB/Simulink. Pulse Width Modulation (PWM) switching is applied to the IGBT gates. A nominal voltage of 240V with 50Hz frequency is applied to run the converter. The simulation results show that PWM switching caused high THD to the circuit. Power Active Filter is used as an attempt to mitigate the harmonic components by compensating the unwanted signal at the resulting waveform. The power active filter is implemented to reduce the THD of the converter. The simulated single-phase AC/AC converter will be beneficial for further studies in improving the performance of electrical mechanism such as the AC machine.
