Abstract : A novel three phase bidirectional AC buck converter circuit using power MOSFET is analyzed for input power factor, harmonic profile and efficiency of the converter for power quality improvement. The equal PWM (EPWM) technique is a used to increase number of pulses per half cycle (P) in order to vary these parameters. The rms value of the fundamental component of the output voltage can be increased by varying the duty ratio (K) of the pulses. It is observed from the simulation results obtained using MATLAB/simulink that the proposed scheme using EPWM technique significantly reduces low order harmonics, eliminates certain harmonics for certain values of P, improves input power factor and hence significantly reduces the filter size of the converter.
