一种用于ZVS四开关Buck-Boost变换器的恒频实时数字控制

In this article, a constant switching frequency real-time digital control scheme is proposed for the four-switch buck-boost converter. With this control scheme, all the power switches can realize zero-voltage-switching, and the ripple and root-mean-square value of the inductor current can be minimized in the whole voltage and load ranges. Since all the control variables in any operation mode are o...
