Abstract
In small scale and large scale applications like automobile industries, domestic appliances such as Refrigerators, washing machine and air conditioning units which use conventional motor technology. These conventional motors have a chacterstics of Low torque, high maintenance and low efficiency. The usage of induction motor enhances various performance factors ranging from higher efficiency, higher torque, high power density, low maintenance and less noise than conventional motors. The main drawback is high cost. In this paper a two leg inverter fed induction motor drive is proposed which uses only four switches and two current sensors compared with six switches, three current sensors in case of three leg inverter fed induction motor drive. Less number of switches and current sensors means less switching loss and low cost. In this paper a two leg inverter fed induction motor drive with two input DC source is proposed.
