Arpit Bohra, Divya Sajeesh, Chintan Patel, Michael Saldanha . Modulation Techniques in Single Phase PWM Rectifier. International Conference on Advances in Science and Technology. ICAST2015, 3 (February 2016), 5-7.
This paper deals with the modulation techniques associated with the single phase pulse width modulated (PWM) rectifier. A PWM rectifier is obtained by replacing the diodes in a bridge rectifier with power electronic switches like MOSFET, IGBT etc. The ON/OFF instants of theses switches can be controlled to approximate input power factor to unity and reduce total harmonic distortion (THD) of input current. A MATLAB simulation of PWM rectifier using hysteresis current control technique is done using simulink and waveforms are analyzed for power factor, THD and ripple in output voltage.
