Interleaved Phase-Shift Full-Bridge Converter With Transformer Winding Series–Parallel Autoregulated (SPAR) Current Doubler Rectifier

The analysis and design guidelines for a two-phase interleaved phase-shift full-bridge converter with transformer winding series-parallel autoregulated current doubler rectifier are presented in this paper. The secondary windings of two transformers work in parallel when the equivalent duty cycle is smaller than 0.25 but in series when the duty cycle is larger than 0.25 owing to the series-parallel autoregulated rectifier. With the proposed rectifying structure, the voltage stress of the rectifier is reduced. Also, the interleaving operation reduces the output current ripple. A 1-kW prototype with 200-400-V input and 50-V/20-A output is built up to verify the theoretical analysis.
