Modelling and simulation of modified unipolar PWM scheme on a single phase DC-AC converter using PSIM

Pulse-width modulation (PWM) of a signal or power source involves the modulation of its duty cycle, to either convey information over a communications channel or control the amount of power sent to a load. This paper presents work on modelling and simulation of modified unipolar PWM applied to a sin...

Description
Summary:Pulse-width modulation (PWM) of a signal or power source involves the modulation of its duty cycle, to either convey information over a communications channel or control the amount of power sent to a load. This paper presents work on modelling and simulation of modified unipolar PWM applied to a single phase DC-AC converter (inverter) as switching control schemes. The harmonic analysis for switching algorithm is done and the best parameters which results in less electromagnetic interference noise produced were chosen to be applied on the inverter using PSIM simulation software. The inverter and its LC filters component value are fixed and carefully selected by considering their volumes and prices as it will be applied in a real hardware to ease any future hardware setup.
