摘　　要：设计的防火卷帘门备用电源采用一片集成脉宽调制电路芯片KA3525A产生两路推挽型PWM信号,通过IGBT驱动后,由自制的高频变压器产生大功率的电压来驱动开闭机。该备用电源在实际应用中得到了肯定。A fire-proof roll door emergency power source has been designed with the PWM inverter technology. The emergency source is implemented using a KA3525A chip to generate PWM wave , driven by IGBT PWM inverter the high-power voltage can be generated instantly by self-made high frequency transformer to drive loads. The efficiency of the device is proved by practice.
