New energy efficient drive for 2 phase induction motor with minimum switching losses
Emerging high volume low power variable speed sc motor drives have the stringent requirements of low cost and compactness. Most of low power, low performance applications use two phase induction motors. New control scheme is proposed for two phase inverter to control two phase induction motor in this paper. The proposed scheme is simple, cost effective and reduces inverter switching losses significantly as four out of six switches operate on fundamental frequency. The objective of the work is to provide cost effective inverter which can induce a change from constant speed to variable speed operation in low power range
