一种改进动态性能的四开关Buck-Boost变换器PWM加移相控制简化实现方法

The four-switch buck–boost converter possesses features that enable both voltage step-up and step-down, and positive output voltage. This converter has gained widespread popularity in applications that require a wide input voltage range. By utilizing pulsewidth modulation (PWM) plus phase-shift control, all power switches can achieve zero-voltage-switching across the entire input voltage and load ...
