基于可变耦合电感的交错式双向Buck-Boost变换器零电压开关控制

This paper investigates an approach for achieving zero-voltage switching of an interleaved bi-directional buck-boost converter over a wide input-output voltage operating range by utilizing a coupled inductor with a variable coupling coefficient. The approach is based on regulating the value of the coupling coefficient by means of a direct current depending on the converter conversion ratio, thereb...
