摘　　要：针对心电图机DC/DC电源进行了设计。以TPS5450 DC/DC转换芯片和MC9S08QG8单片机为核心的多路DC电源,包括DC/DC转换电路,充电电路,升压电路,单片机电路等,通过该电路来输出多路电压,利用软件编程实现对输出的多路电压值实时检测,并交由上位机处理,从而保证系统的可靠性和稳定性。实验结果表明,该DC/DC开关电源设计符合心电图机电源的要求,运行安全稳定可靠。The DC / DC power of ECG Machine is designed. TPS5450 DC / DC converter chip and MC9S08QG8 microcontroller are used as the core,multi-channel DC power is designed,including DC / DC converter circuit,charging circuit,the boost circuit,microcontroller circuit and so on. The above circuits are used to supply the needed voltage value. The real detection of multi-channel output voltage value is implemented by program. Then the result is processed by the host computer. So the reliability and stability of the system is ensured. The experimental results show that the DC / DC switching power can meet the ECG machine power requirements. The system runs safely and reliably.
