Abstract
In this paper, a novel compensation scheme for ac-dc pwm converters under switching device fault status has been proposed, along with an effective diagnosis method. With the proposed scheme, the pwm converter can be properly operated even when one of the switching devices of the converter is out of control, so that it may ensure the performance and reliability of pwm converters to be increased. The developed scheme is explained in theoretically and the validity is verified by the informative simulation and experimental results in detail.
