一种具有无损电流检测和无缝切换的高效率四开关Buck-Boost变换器控制方法

The quadrilateral control method for four-switch Buck–Boost converter can enable all of the power switches to achieve zero-voltage-switching (ZVS), thereby achieving high power density. However, the inductor current requires to be sensed and regulated to ensure the realization of ZVS, which will introduce the additional losses and degrade the efficiency. In this article, a high-efficiency control ...
