An adjustable speed drive for single-phase induction motors has a low-cost structure including a rectifier and a two-switch inverter. During full-speed operation, power is supplied directly from the AC power system to the main winding of the motor andfrom the inverter at line frequency but phase-shifted from the line voltage to an auxiliary winding of the motor to develop start up torque for the motor.
