摘要
为提高纯电动汽车车载DC/DC变换器工作的稳定性与安全性,对常规反馈电路存在的问题进行分析和改进,同时对主电路进行限流、过压和过温等安全保护性能的设计。最后通过实验证明:改进反馈电路后的变换器输出电压更稳定,且输出电压纹波较小。
In order to improve the stability and safety of converter, the problem existing in conventional feedback circuit is analyzed and settled, and the design of security protection performance of cur- rent limit, over voltage and temperature has been added in main circuit. The experiment proves that the output voltage of conveter with improved feedback circuit is more stable and the output voltage ripple is smaller.
