A buck converter (buck converter) is a DC-to-DC power converter that lowers the voltage from the source to the load (in drawing a smaller average current). It's a type of switching power supply (SMPS) with at least two semiconductors (a diode and a transistor, though modern buck conv...
在非隔离型DC-DC变换器中,Buck变换器只具备降压功能;LLC谐振变换器的输入电压越高,效率越高;使用Buck变换器作为前级变换器不利于整体工作效率优化。传统Buck-Boost变换器和Cuk变换器的输入输出电压极性相反。因此,传统Buck变换器、Buck-Boost变换器和Cuk变换器均不适合级联变换器的前级方案。文献[11-13]采用了级联式...
