摘要

A high performance improved Bridgeless AC - DC Power Factor Correction (PFC) converter is presented, which eliminates conventional diode bridge rectifier with stiff output voltage regulation. In-order to get high efficiency compared to the conventional system, a compact converter is designed which make use of the body diodes of switches instead of having separate diodes. The positive output bridgeless converter can operate in discontinuous conduction mode and facilitate both.buck and boost operation. This single stage AC - DC converter does not need any additional filters in the source side to improve power quality. Also, the resultant THD is very low even in the absence of filters.
