摘要
随着高频电力电子器件的发展,高性能的开关式交流调压得到广泛应用。在介绍交流调压原理和开关型斩控式交流调压电路的基础上,系统采用stc12c5608ad单片机产生PWM信号,通过驱动电路对IGBT开关管进行控制。最后给出了仿真及实验波形,结果表明斩波控制交流调压器具有易滤波,输出电压、电流波形好的优点。
With the development of high power electronic devices, high-performance switch mode AC voltage is widely used. In the introduction of AC voltage regulator principle and chopped AC voltage regulator circuit, the system uses PWM signal of stc12c5608ad microcontroller to control IGBT switch tube by driving circuit. Finally, the simulation and experimental waveforms are provided, the results show that the AC voltage regulator by choppd has aood advantaae of easy filter, aood OUtDUt voltaae and current waveforms.
