Recent developments in power electronic device technology promises faster switching capability at high power. The hybrid pulse width modulation method which requires two of the four switches in a full bridge inverter are used, and enable pulse pattern operation at high frequency. The use of two level switching instead of three level switching enables the use of higher frequency for given computation time delay. The proposed control scheme is implemented using bi-polar junction transistors (BJT)
