Research on plasma dynamic matching power supply applicable for sludge disposal

随着等离子体技术应用在污泥处理中的不断深入,对于等离子体电源性能的要求也越来越高,因此文中重点研究了污泥处理装置中的等离子体电源的动态匹配功能。采用三相不可控整流电路,IGBT全桥逆变电路,DC侧Buck斩波功率调节和频率自动跟踪算法的策略。最后通过Simulink对电源系统进行仿真,验证了系统的正确性和动态匹配算法的有效性。

With the constant deepening application of the plasma technology to the sludge disposal,the performance requirement of the plasma power supply is getting higher and higher. Therefore,the dynamic matching function of the plasma power supply in the sludge disposal device is emphatically researched in this paper. The three-phase uncontrollable rectifying circuit, IGBT full-bridge inverter circuit,DC-side Buck chopped wave power regulation and frequency auto-tracking algorithm strategy are adopted. The correctness of the system and the effectiveness of the dynamic matching algorithm are verified by simulating the power supply system using the Simulink.
