摘　　要：采用C8051F040和AD7520构成开关电源的数字调节系统,以Boost变换器作为开关电源的主电路,以TL494作为开关电源的控制芯片,研制了具有自恢复过流保护功能的高效、程控开关电源,并用实验结果说明了设计方案的正确性和可行性。The digital tuning system of the switching power supply is composed of C8051F040 and the AD7520. The high effective and program-controlled switching power supply with self-reset and the overflow protection functions is developed,which takes the Boost converter as the main circuit and the TL494 as the control chip. The experimental result explains accuracy and the feasibility of the designed proposal.
