Abstract
A three-phase interleave converter with a TSSC includes: a filter circuit, a PFC circuit, a star connection between the filter circuit and the PFC circuit, and a second capacitor; where an output end of the filter circuit is connected to an input end of the PFC circuit by using a conducting wire; the star connection is set on the conducting wire connecting the filter circuit and the PFC circuit; one end of the star connection is connected to the conducting wire and the other end of the star connection is connected to one end of the second capacitor; and the other end of the second capacitoris connected to an input wire. By using the foregoing solution, the number of capacitors is reduced from the original three to one. Therefore, fewer capacitors are used, and the volume is further reduced, thereby increasing the power density.
