摘　　要：为了克服传统强脉冲光治疗机中电源系统的不足,采用单片机控制IGBT的开通与关断时间,以实现高速可控的充电过程,设计了基于IGBT斩波电路的"母子"式电容充电电源。结果表明,该电源电路安全可靠,在工作电压150V的情况下,可以实现大于2kW的电功率输出,并且输出能量均匀平稳,可以作为强脉冲光治疗机的电源系统。In order to overcome the disadvantages of the power system of the intense pulsed light equipment, a ＂main- subordinate＂ capacitive charging power circuit based on the IGBT chopper circuit was designed. The on and off-time of IGBT was controlled with the micro-chip computer to achieve high-speed and controlled charging process. The experiments prove that this circuit is not only safe but also can achieve the electric output power larger than 2kW when the operating voltage is 150V, and the output energy is uniform. The ＂main-subordinate＂ capacitive charging power circuit based on the IGBT chopper circuit can be adopted in the power of the intense pulsed light equipment.
