一种具有宽ZVS范围和自动均压功能的双极性直流微电网无输入电流纹波DC-DC变换器

A dual-active-bridge (DAB)–based bipolar dc–dc converter with auto-voltage-sharing is proposed for dc microgrids in this article, where an integrated interleaved boost cell with a fixed duty cycle of 0.5 for the primary active-bridge is utilized. As a result, the input current ripple-free is realized. The primary and secondary active bridges are connected by two high-frequency transformers. Two pr...
