In this study, a zero voltage transition (ZVT)–zero current transition (ZCT) pulse-width modulated (PWM) multiphase synchronous buck converter (SBC), with an active auxiliary circuit is proposed, that reduces the stresses and enhances the efficiency abating the switching and conduction losses of the converter. The important design feature of ZVT–ZCT PWM multiphase SBC converters is the placement of resonant components that pacifies the switching and conduction losses. Due to the ZVT–ZCT, the resonant components with low values are used that results in the increase of switching frequency. High current multiphase buck converters found applications in the advanced data control, solid state lasers, communication equipment, Pentium processors etc. The ZVT–ZCT operation of the proposed converter is presented through theoretical analysis. A simple design method for the auxiliary circuit is discussed. The characteristics of the proposed converter are verified with the simulation in the PSIM co-simulated with MATLAB/SIMULINK environment and validated with experimental results.
