摘　　要：本文针对某型野外电台供电电压精度高、动态响应快的要求,采用TMS320LF2407A型DSP为主控芯片、推挽式变换器为主电路、PWM为控制方法研制了一利用太阳能的25V/5A直流稳压电源。应用积分分离式数字PID调节器提高了电源动态响应速度和输出电压精度,使得电源在负载突变和满载输出(5A)时,输出电压的响应速度和纹波电压分别达到0.2s和94mV。实际应用结果表明,该电源不仅完全满足野外电台供电要求,还具有输出电压精度高、稳定性好、动态响应快、携带方便等优点。According to the requirement of a wild-radio＇s power supply, a 25 V/5 A solar DC power supply with high precision and quickly dynamic response is developed. The CPU is TMS320LF2407A, the main circuit is pull-push DC/DC converter, and PWM control method has been used too. The accuracy and the dynamic response are greatly improved because of the use of a digital PID regulator. So the response time is only 0.2 s when the load current achieves 5 A from 1 A, and the ripple voltage is only 94mV when the load current is 5 A. The results of application proved this solar DC power supply is not only fully satisfied with the requirement but also have the advantages of precise output voltage, high stability, quickly dynamic response etc.
