矿用本安电源上电时，容易因负载电容充电造成本安电源误动、可靠性变差；

When the mine intrinsic safe power was energized, due to the loading, the mine intrinsic power would have miss actions and poor reliability occurred by the capacitor charging.

为解决以上问题，对负载端直流-直流（DC-DC）电源模块进行研究，提出一种新的本安型DC-DC隔离电源模块的设计方案。

In order to solve the above problems, a study on the DC-DC power modular of the loading terminal was conducted and a new design plan of the intrinsic safe DC-DC isolated power modular was provided.
