[Abstract]:Aiming at the calibration of defibrillation analyzer, a defibrillation energy generator is developed, which provides the technical support for the safety of the public. The control circuit of defibrillation energy generator based on conventional single-phase exponential wave based on IGBT is studied. The defibrillation energy control circuit system based on IGBT is proposed, and the overall frame of the whole system is constructed. The hardware circuit of the system is designed, including the design of linear stabilized power supply, the gate drive design of bootstrap method and the simulation of Multisim circuit. The PWM signal with certain duty cycle is output by STM32 to control the IGBT turn-on and interrupt. The results show that the circuit control system works normally, stable and reliable, the output single-phase attenuation exponent wave and discharge time data are accurate. Finally, the repetitive experiment of the designed IGBT control system is carried out. Verify the accuracy of the system to release single-phase wave energy. It meets the requirements of calibration analyzer and provides the basis for further research on the full-bridge inverter circuit of defibrillation energy generator and the design of high-precision pulse shunt divider for energy data acquisition.
