| Abstract |
This paper presents two different commutation methods for PWM rectifier section of the converter without dc link components. The first method is so commutated that each switching device of the bi-directional switches are controlled independently with sensing dc current direction. The second method is so commutated that the commutation of the PWM rectifier is forced to occur only in the zero voltage vector(V0, V7) period of the inverter. The main advantage of these methods is that the snubber circuits of the PWM rectifier section can be removed. Adopting the second method, not only the loss of the snubber circuit but also the switching loss in PWM rectifier section can be reduced. These methods have been verified by computer simulation on an induction motor drive. |
