LLC型串并联谐振变换器参数分析与运用。还要我说什么的，就是这么点-LLC-type series-parallel resonant converter parameter analysis and application. What should I say, that is such a point

数字控制的全桥LLC谐振变换器的软启动程序，开关频率从300kHz降为谐振频率(Soft start program of digital controlled full bridge LLC resonant converter, the switching frequency is reduced from 300kHz to resonant frequency)
