一种宽输入电压范围Buck+LLC级联变换器的动态控制方法

DC–DC converters with a wide input voltage range have earned numerous daily applications in the industry. An example is power systems for electric vehicles, where $LLC$ converters with remarkable features have also been deployed to provide isolation. It is, therefore, common to find a front buck converter cascaded to a back $LLC$ converter, where their intermediate bus voltage is set low to accomm...
