POWER FACTOR CORRECTION AND DC-DC MULTIPLEXING CONVERTER

The present invention provides a power factor correction and DC-DC multiplexing converter. One end of an inductor is selectively connected to a mains supply or a positive electrode of a battery. A first rectifier bridge arm with a first intermediate node and a second rectifier bridge arm with a second intermediate node are separately connected between a first node and a second node, the first intermediate node is connected to the other end of the inductor, and the second intermediate node is connected to a neutral point. A first semiconductor switch controls conduction between the first node and the second node. A second semiconductor switch controls conduction between the second node and a negative direct current bus. A third semiconductor switch controls conduction between the neutral point and a negative electrode of the battery. The positive and negative direct current buses are configured to provide a direct current output.
