四开关Buck-Boost变换器的能量模型

The four-switch buck–boost (FSBB) topology is often used in combination with other isolated converters to extend the voltage range capability of the overall structure. In such applications, the duty-cycles of the two legs of the FSBB are independently controlled, and a phase shift is typically used to shape the inductor current ripple and, thus, achieve zero voltage switching.
