摘　　要：研究了基于脉冲密度调制(Pulse Density Modulation)控制策略的串联谐振逆变电晕处理电源。PDM的基本思想是在一定的调功周期内使交流输出端产生方波电压或者是零电平电压,这样即使电晕放电负载具有很强的非线性也可以宽范围内控制功率输出。对于该电晕处理电源进行了仿真与实验,所得结果验证了理论分析。A pulse density modulated (PDM) series-resonant inverter for corona discharge process is studied. The PDM inverter produces either a square-wave voltage state or a zero voltage state at its AC output terminals to control the average output voltage in one power adjusting cycle. So the output power can be controlled in wide range, even if the corona discharge load has a strong nonlinear characteristic. The results of simulation and experiment have proved the theory analysis.
