摘　　要：为了促进电晕法烟气脱硫的工业应用进程,本文设计了高可靠性的交直流叠加电源代替常规的火花隙脉冲电源。电源由交-直-交变频电路、全桥不控整流电路和串联谐振电路组成。本文重点分析了串联谐振电路的工作原理,提供了实验参数设计依据。在实验中,改变谐振电感值,得到最优的工作状态;通过加大反应器上的电压幅值,使反应器由流光放电向火花放电过渡,得出两种状态下电源的波形,将实验结果与理论分析进行比较,验证了理论分析,并对电源的可靠性进行了考核。In order to accelerate the industrial application of streamer discharging FGD, a high reliable AC ＋ DC power supply is designed, which can replace the traditional pulse generator with spark-gap switches. The power supply includes AC-DC-AC converter, full-bridge diode rectifier and series resonant analyzed in detail, providing the experiment parameters. The optimal circuit. The principle of series resonant part is resonant condition can be obtained by changing resonant inductance. A transition from streamer discharge to spark discharge happens to the reactor by incrbasing its voltage amplitude. The theoretical analysis and the reliability of the power supply are verified according to these experiment waveforms.
