buck boost

基本解释

This leaves a switching implementation, either a step-down buck or step-up boost topology.
因此，我们只能选择开关式实施方案，或者采用步降降压拓扑，或者采用步进升压拓扑。
In this paper, current detection circuits which could be used for hysteresis current control mode buck-boost DC-DC converters were designed.
本文针对滞环电流控制模式buck-boost DC-DC转换器，设计了其中的电流检测部分。
The difference of output voltage of inverter and 220V is set as control signal, controller change the PWM signal to regulate buck-boost converter and three-phase rectifier.
以逆变器输出的电压和220V的差值作为控制信号。设计控制器根据控制信号改变直流变换器和三相可控整流的PWM控制信号。
