| 摘 要： | 该文介绍了一种采用脉冲密度调制（PDM）控制策略的串联谐振型塑料薄膜表面处理电源的研制。PDM控制策略的采用可以确保电源工作于定频和定压，并且可以方便地实现开关管的软化。除满功率情况外，开关管的平均开关频率都低于谐振频率，降低了开关损耗。给出的仿真和实验结果验证了这种脉冲密度调制策略的有效性。

| Abstract: | This paper presents a pulse density modulated (PDM) series resonant inverter developed for plastic film surface treater. The use of the PDM inverter enables the constant frequency and voltage. Moreover, it can achieve zero-voltage-switching (ZVS) in all the operating conditions and low turn-off loss at switching transition. The average switching frequency in the PDM control is lower than the resonant frequency except for full power, resulting in low loss. Simulation and experimental results are presented to illustrate the effectiveness of the density modulation control strategy. |
