一种用于宽电压范围中压功率转换的双向模块化多电平谐振DC-DC变换器

The arm inductor is found to cause the loss of soft switching in modular multilevel resonant dc–dc converters, so a full-range soft switching converter with wide voltage gain is proposed in this article. The modular multilevel structure and the CLLC resonant tank are utilized in the converter for isolated and bidirectional power conversion in medium-voltage applications with high efficiency. Wide ...
