摘要
为了满足宽供电范围需求,开发设计了一种电感耦合式Step-down CUK变换器开关电源,对该变换器的输入输出电流进行了稳态分析,表明变换器具有的电流连续特性,有利于提升变换器的功率密度;提出了一种变频控制策略及其实现方法,解决了变换器的稳定性问题。试验验证及批量装车考核表明该设计具有实用性。
To fulfill the requirement of wide-range power supply, an inductor-couple step-down CUK converter was designed. Input and output current of the converter in steady state was analyzed, which showed the continuous current feature, in favour of improve converter power density： and a kind of variable frequency control strategy and its realization method were presented, which solved the stability problem of the convener. Experiment and batch on-board test validated the proposed design.
