A Parallel Interleaving Converter with Soft-switching

This paper proposes a soft-switching interleaved Boost converter and control method,it can achieve high power factor,and turn on at zero current and turn off at zero voltage.The paper presents the work theory of the electric circuit and the analysis of various mode,and gives the calculation and design of key parameter.Finally,the simulation and experiment are given to verify the validity of the proposed theory.The converter has extensive applied foreground in the high-power single-phase power factor control.
