buck boost

基本解释

This leaves a switching implementation, either a step-down buck or step-up boost topology.
因此，我們衹能選擇開關式實施方案，或者採用步降降壓拓撲，或者採用步進陞壓拓撲。
In this paper, current detection circuits which could be used for hysteresis current control mode buck-boost DC-DC converters were designed.
本文針對滯環電流控制模式buck-boost DC-DC轉換器，設計了其中的電流檢測部分。
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.
以逆變器輸出的電壓和220V的差值作爲控制信號。設計控制器根據控制信號改變直流變換器和三相可控整流的PWM控制信號。
