摘　　要：针对矿用本安电源Buck变换器中开关器件在传统的硬开关高频模式下工作,存在器件温度升高及开关损耗等问题,提出了一种适用于矿用本安电源的Buck电路软开关,实现了其开关器件的软开通和关断。应用MATLAB仿真进行了验证,能够有效地降低开关损耗,保证了本安电源的安全运行。For mine safety power supply switch device in the Buck converter work hard switch in the traditional high frequency mode, some problems such as device temperature and switch loss, proposes a Buck for mine safety power supply circuit soft switch, implements the soft open and shut off the switch device. The simulation of MATLAB is verified, and it can effectively reduce the loss of the switch and guarantee the safe operation of the power supply.
