A near unity power factor input stage with minimum control requirements for AC drive applications
Abstract
Conventional AC induction motor drives use a PWM voltage source inverter (VSI) fed from a diode rectifier. In retrofit applications, due to voltage drops and the inverter voltage gain, six-step operation of the inverter is required at rated speed, resulting in large low order harmonic current and torque components. To allow the inverter to operate in the PWM mode at rated speed, a synchronous rectifier is proposed in this paper to slightly …
