Abstract:

This paper proposes a family of PWM modulation strategies for boost full-bridge(FB)converters. The modulation strategies can be classified into two kinds according to the turn-on sequence of the diagonal switches. The concept of leading switches and lagging switches is introduced to realize soft-switching. According to the soft-switching realized by the leading switches and the lagging switches, two kinds of soft-switching techniques for PWM boost FB converters yield: zero-current-switching(ZCS)and zero-current and zero-voltage-switching(ZCZVS). Simulation results verify the analysis.
