摘　　要：针对现有气体开关频率低、幅值不易控制的缺点,以固体开关绝缘栅双极型晶体管(IGBT)为主要开关元件,由单片机来控制频率和占空比的调节,通过脉冲变压器升压和整形电路的整形,得到高频高压方波电压。脉冲电压频率可以在1～15 kHz之间任意调节,电压幅值可在0～20 kV之间连续可调。电源同时具有良好的过压和过流保护作用。Solid state switch insulated gate bipolar transistor （IGBT） is made as main switching elements. The frequency and duty cycle are regulated by microcontroller. High frequency and high voltage square wave voltage is achieved by step-up of pulse transformer and shaping of shaping circuit. The shortcomings of low switching frequency and amplitude with difficult coercion which existing gas switch has are overcome. The frequency of pulse voltage can be adjusted between 1-15 kHz. Voltage amplitude can be continuously adjusted between 0-20 kV. Power has good role on overvoltage and overcurrent protection at the same time.
