TITLE

Simulation of Multi step DC-DC converter using APS Control for Fuel Cell Power System

ABSTRACT

This paper analyzes a novel pulse width modulation (PWM) scheme for alternate phase shift (APS) isolated boost converter with voltage booster for fuel cell power system by combining APS control and traditional isolated PWM control. The APS control is used to reduce the voltage stress on switching devices in light load while the traditional interleaving control is used to keep best performance in heavy load. The mathematical analysis is also presented to deliver the feasible power ranges. Based on the analytical calculations, a full range control combining APS and traditional isolated control is proposed. Zero voltage switching is achieved for alternate phase switches. Finally, it is verified by simulated results.
