Power conversion system and method. The system includes a first capacitor including a first capacitor terminal and a second capacitor terminal, a second capacitor including a third capacitor terminal and a fourth capacitor terminal, and a plurality of diodes including a first diode, a second diode, a third diode, and a fourth diode. The first diode is coupled to the second diode at a first node, the second diode is coupled to the fourth diode at a second node, the fourth diode is coupled to the third diode at a third node, and the third diode is coupled to the first diode at a fourth node. Additionally, the system includes a fifth diode including a first anode and a first cathode and a sixth diode including a second anode and a second cathode.
