摘要
介绍了DC/DC变换器电路的基本工作原理。采用移相控制器UC3879为控制核心,设计出了对DC/DC功率变换器实现恒流输入控制的实用电路。试验结果证明系统性能优良。最后给出了在软开关条件下的实验波形。
The working schematic of the power DC/DC converter circuit topology is introduced. An applied circuit of the converter is designed. The converter, which is controlled by the UC3879, works in constant current states. The experimental results show the converter has excellent electrical characteristics, and the experimental waves under the soft-switching condition are shown.
