基于串并联混合开关控制电容网络的变增益LLC变换器

In this article, a variable-gain LLC converter with a series–parallel hybrid switch-controlled capacitor network is proposed. By tuning the duty cycle of two controlled switches, the resonant capacitance of converter can be regulated and will slightly shift the parameters of resonant tank. Meanwhile, the added switches will be turned on at the zero-crossing point of resonant current to guarantee s...
