Current high-frequency and high-voltage constant-DC power supply is one of the core cel technologies in energy system of Inertial Conifnement fusion. After use of wet electrostatic precipitator, it can solve the problems of low efifciency of dust removal caused by the change of lfue gas characteristic and safeguard much dust col ections of wet electrostatic precipitator. The power factor of DC power source with high frequency, constant lfow and high voltage is high and the transferring efifciency is high too, it shows a notable effect in energy saving.%针对燃煤电厂排放粉尘浓度≤5mg/m3的标准，燃煤电厂和钢铁厂脱硫烟气深度处理装置应运而生，即湿式电除尘器技术。然而湿式电除尘器烟气为饱和湿烟气，加之采用喷淋方式清灰，烟气特性变化幅度大，电场工作很不稳定，造成除尘效率的降低。高频恒流高压直流电源是惯性约束核聚变能源系统中的核心单元技术之一，用于湿式电除尘器后，可以很好地解决烟气特性变化造成的除尘效率低的问题，能够有效地保护湿式电除尘器收尘极。高频恒流高压直流电源功率因素高，转换效率高，在节能方面有显著效果。
