用于宽电压范围运行的双向DC/DC谐振变换器双电压整流调制

It is difficult to achieve wide voltage range for full-bridge-based bidirectional resonant dc/dc converter due to the large resonant current caused by the small magnetizing inductance. A half-bridge modulation was proposed to extend the output voltage range by offering an additional step-down voltage step of 0.5 normalized gain. But in backward operation, the converter cannot provide the two-times...
