Patent ID: 11171557

Abstract:
A power converter includes a full-bridge conversion circuit. The full-bridge conversion circuit includes a first leg and a second leg. The first leg includes at least two switches coupled to each other at a first node, and the second leg includes at least two switches coupled to each other at a second node. The power converter further includes an AC filter. The AC filter includes a first inductor, a second inductor and a capacitor. The first inductor includes a first end coupled to the first node and a second end could be couple to a grid. The second inductor includes a first end coupled to the second node and a second end could be couple to the grid. The capacitor includes a first end coupled to the second end of the first inductor and a second end coupled to the second leg. The first end of the capacitor is electrically coupled to the second end of the first inductor during a cycle of an AC voltage of the grid.
