用于宽输入电压范围应用的变频零环流移相调制双相LLC谐振变换器

This article proposes a novel dual phase LLC resonant converter with an improved variable frequency-based zero circulating current phase-shift modulation scheme for wide input voltage applications. The presented topology employs a six-switch dual active bridge with two output ports reducing the voltage stress across upper and lower switches to half of the input voltage. The proposed modulation sch...
