Abstract:
In accordance with presently disclosed embodiments, a 5-switch power conversion circuit that improves the power conversion efficiency (PCE) of a DC-DC converter with a double chopper topology is provided. The power conversion circuit adds minimal complexity through an additional switch, while preserving the benefits of a 3-level boost converter topology. The disclosed power conversion circuit uses four switches that are arranged in a 3-level boost converter arrangement, and a fifth switch that is connected in parallel with two of the other switches. The fifth switch helps to reduce the conduction power losses through the DC-DC converter by providing a one-switch ON-state conduction path instead of a two-switch path during part of the DC-DC power conversion cycle.

Claim (Index 15):
The method of  claim 12 , further comprising:\n directing power from one or both sides of the DC bus via current flowing through the at least one inductor, one or both capacitors, and two of the switch transistors to store energy in the at least one inductor; and directing current through the at least one inductor, the voltage supply, and a free-wheeling diode of the fifth switch transistor to output the stored energy from the at least one inductor to the voltage supply.
