摘要
介绍了无光耦隔离式DC／DC变换器通行的设计都是将输出电压载波成高频电压传递到一次侧进行反馈控制的。这里提出另一种方法，在一次侧占空比进行预调节，二次侧再进行调节，反馈闭环只在二次侧进行，并阐述其工作原理，给出实验结果。
The traditional designed method of No -opto-isolated DC/DC Converter is that changing the output voltage into high-frequency signal first and then transferring high-frequency signal to primary side for feedback controlling is introduced. Another method is proposed,which is controlling the circuit in primary side firstly,and then controlling the circuit in secondary side. Besides,the feedback loop controlling circuit is placed in secondary side. Then the working principle of the circuit are described and the experimental results are gived.
