摘　　要：研制了一种新型的用于静电除尘的高频高压直流发生器 (2 0kHz <逆变频率 <4 0kHz,长时间输出电流最高2 0 0mA ,短时可耐 5 0 0mA ,输出电压峰值 10 0kV ,直流波纹系数 0 .5 % ) ,电源采用输出可整定的直流高压发生器 (最高可达 10 0kV)和有效值可调整的方波交流电压 (峰值 10kV ,有效值根据电流设定 )相叠加的结构 ,从而使电源输出电压始终稍低于产生火花的放电电压 ,保证了除尘效果 。A new type of high frequency high voltage DC generator that can be applied to electrostatic precipitation is developed. The power supply utilizes the structure which is the combination of the DC adjustable high voltage generator and the variable voltage high frequency square generator. So the output voltage of power supply is always lower than the discharge voltage that generates the spark, which ensures the effect of precipitator. The performance of this kind of high voltage DC power supply is superior to the conventional one.
