摘要
在煤矿井下供电系统出现问题时,需要应急供电系统切换供电,保证通风机的正常运行。针对传统逆变器的工作缺陷,设计用于煤矿井下局部通风机应急供电系统的Z源逆变器,详细介绍主电路的工作原理,并对Z源逆变器SPWM控制进行仿真实验。
When problems occur in the power supply system of underground coal mine, emergency power supply system should be switched to ensure the normal operation of ventilators. Aiming at the shortcomings of traditional inverters, Z-source inverters were designed for emergency power supply system of local fan in coal mine. The working principle of main circuit was introduced in detail,and the SPWM control of Z-source inverters was simulated.
