A new interleaved ZCS PWM boost converter

In this paper, a new interleaved zero-current-switching PWM boost converter is introduced which uses only one auxiliary switch to provide soft-switching condition. In the proposed interleaved converter, soft switching is obtained for all semiconductor devices. Thus, the reverse-recovery losses of boost diodes are reduced. In addition, high efficiency is achieved due to reduction of switching losses. The converter is analyzed and the design procedure is discussed. Simulation results are presented to verify the validity of theoretical analysis.
