摘要
提出了一种能够有效改善DC-DC变换器动态性能的方案。该方案是在全桥电路基础上并联一单端正激变换电路,使变换器负载从10％轻载突加到100％满载时,其暂态过程小于1μs,输出电压达到设计要求。文中对具体电路进行了详细分析,并通过仿真进行了验证。
A new Scheme was presented to efficiently improve the dynamic performances of DC-DC converter. It parallels a single end forward conversion circuit on the basis of the full bridge circuit to make the transient process within 1 us form 10% to 100% step load and the output voltage meet the designed requirement. The paper analyzes in detail the specified circuit and verifies it by emluation.
