宽电压范围谐振式四开关反相Buck-Boost DC/DC变换器的软开关控制

A resonant four-switch inverting buck–boost converter is a good choice for dc/dc applications that require an inverting voltage solution. A soft-switching control scheme with four segments of resonance current has been examined using duty ratio and phase shift as control variables. As a result, the rms value of the resonance current is low compared with discontinues current mode (DCM), which is di...
