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 1):
A power conversion system, comprising:\n a 5-switch power conversion circuit comprising:\n a voltage supply; \n at least one inductor coupled to the voltage supply; \n a DC bus comprising a first capacitor on a positive side of the DC bus and a second capacitor on a negative side of the DC bus; \n a first switch transistor, a second switch transistor, a third switch transistor, and a fourth switch transistor each coupled between the at least one inductor and the DC bus in a 3-level DC-DC boost circuit configuration; \n a fifth switch transistor disposed between the at least one inductor and the first, second, third, and fourth switch transistors, wherein the fifth switch transistor is coupled in parallel to the second and third switch transistors; and \n a controller communicatively coupled to the first, second, third, fourth, and fifth switch transistors, wherein the controller is configured to output signals to the first, second, third, fourth, and fifth switch transistors to independently control the positions of the first, second, third, fourth, and fifth switch transistors and wherein the controller is configured to output a signal to the fifth switch transistor to turn the fifth switch transistor to an ON-state when both the second and third switch transistors are in an ON-state such that current will flow through the inductor and the fifth switch transistor instead of through the inductor and the second and third switch transistors.
