PROJECT TITLE :
Interleaved Phase-Shift Full-Bridge Converter With Transformer Winding Series–Parallel Autoregulated (SPAR) Current Doubler Rectifier
The analysis and design pointers for a 2-part interleaved part-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 zero.twenty five however in series when the duty cycle is larger than 0.twenty five because of 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 one-kW prototype with two hundred-400-V input and fifty-V/twenty-A output is built up to verify the theoretical analysis.
