Analysis of current doubler rectifier based high frequency isolation stage for intelligent transformer

This paper proposes new topology for high frequency isolation stage of intelligent transformer based on bi-directional current doubler rectifier (CDR). Paper provides complete steady-state analysis of the proposed bi-directional CDR in boost mode. To facilitate the understanding of operation, the converter equivalent circuits for each operating mode with corresponding waveforms are presented. Also, mathematical analysis is done and compared with simulation results.
