摘　　要：目的 :研制一种除颤能量标准源,该标准源能释放单相波、双相波2种除颤脉冲,并且能显示释放能量标准值。方法:利用单端反激励充电方式给储能电容充电,通过脉冲宽度调制(pulse width modulation,PWM)驱动由绝缘栅双极型晶体管(insulated gate bipolar transistor,IGBT)组成的H桥控制电容放电,同时通过分压器、分流器分别采集脉冲电压和电流值,并通过STM32微处理器计算除颤脉冲能量值,最后通过显示模块显示释放的脉冲能量准确值。结果:所研制的除颤能量标准源可释放单相波和双相波2种波形除颤脉冲,并且显示的除颤脉冲能量值精度优于±2%或±1 J。结论:该除颤能量标准源可作为除颤器分析仪溯源校准的标准器具,可完善除颤器释放能量准确度的溯源体系。Objective To develop a standard defibrillation energy source which can output monophasic and biphasic de-fibrillation impulses and can display standard energy values.Methods The storage capacitor was charged by single-end flyback transformator and discharged through the H bridge composed of insulated gate bipolar transistor （IGBT）. Impulse voltage and current were collected by divider while discharging, and the energy value was calculated by STM32. The en-ergy value and waveform were displayed through the control module.Results The energy source could output both monophsic and biphasic waveforms, and the accuracy of displayed value was higher than ±2% or ±1 J.Conclusion The standard defibrillation energy source can be used as standard device for defibrillator analyzer, and the metrological trace-ability system of defibrillation energy may come to be completed.
