| 摘 要： | 矿用本安型开关电源是本安型电气设备的最关键组成部分。针对矿用本安电源反馈回路中含滞后环节时,输出电压会含有一些远低于开关频率且幅度较大的纹波,造成输出电压不稳定,开关变换器效率降低,负载可靠性变差,为解决以上问题,对开关电源模块进行研究,提出一种新的变换器设计方案,利用PSPICE对变换器进行了仿真。该设计不仅可以提高变换器的整体性能,而且可使变换器的输出达到最优。对于其他形式的变换器此法可以推广应用。

| Abstract: | Mine-used switching power supply is significant composition of intrinsic safe equipments.In allusion to fact that there is plenty of ripple in output voltage when a delay exists in feedback loop of a converter,and this phenomenon will result in instability of output voltage and reduce efficiency,a step-down converter buck is used for investigating.A new approach is put forward,and PSPICE simulation is employed.This scheme not only can enhance whole performance,but also can make output voltage optimal.For other kinds of converters,this approach can be generalized to application. |
