| 摘 要： | 针对传统交错并联Buck变换器存在占空比小的问题,将三绕组耦合电感引入反激变换器,设计了一种交错并联三绕组耦合Buck变换器。分析了该变换器中开关管和输出二极管的电压应力,进而得到该变换器的输出电压增益,并对该变换器拓扑进行了优化。仿真和实验结果表明,该优化拓扑可有效抑制开关管两端的电压波动,降低开关管的电压应力。

Design of interleaved three-winding coupling Buck converter |
| |
| Abstract: | In view of problem of small duty cycle existed in traditional interleaved Buck converter,an interleaved three-winding coupling Buck converter was designed by introducing three-winding coupling inductance into flyback converter.Voltage stress of switching tube and output diode of the converter were analyzed,then output voltage gain of the converter was achieved,and topology of the converter was optimized.The simulation and experiment results show that the optimized topology can suppress voltage fluctuation between both ends of switching tube effectively and reduce voltage stress of switching tube. |
