Abstract

Fuel cells are considered to be one of the most promising sources of distributed energy because of their high efficiency, low environmental impact scalability. Unfortunately, multiple complications exist in fuel cell operation. This paper examines a novel pulse width modulation (PWM) scheme for two-phase interleaved boost converter with voltage multiplier for fuel cell power system by combining alternating phase shift (APS) control and traditional interleaving PWM control. The APS control is used to reduce the voltage stress on switches in light load while the traditional interleaving control is used to keep better performance in heavy load. The boundary condition for swapping between APS and traditional interleaving PWM control is derived. Based on the aforementioned analysis, a full power range control combining APS and traditional interleaving control is proposed. Loss breakdown analysis is also given to explore the efficiency of the converter Taking into account the above investigation, a full power reach control joining APS and customary interleaving control is proposed.
