Abstract :
This paper presents an active clamping modified push-pull converter using the three-state switching cell (TSSC). The active clamping circuit allows soft switching in the converter switches for a determined load range. Thus, switching losses are reduced and the converter efficiency is improved. Qualitative and quantitative analyses, a design example and experimental results are presented for the proposed converter. The experimental tests are performed on a 1 kW laboratory prototype, which steps the input voltage from 48 V to 400 V.
