Methods of Eliminating Abnormal Phenomena Observed in Low-Voltage Output Paralleled Converter System

摘要

Methods for solving abnormal phenomena observed in low-voltage output paralleled converter system using synchronous rectifiers are discussed. The abnormal phenomena such as reverse power-flow and self-oscillation are described and causes of them are discussed. Conventional current-sharing controllers are used to avoid the phenomena; the results of which are confirmed by experiment.
