摘要
以静电除尘器供电电源用20kHz高频变压器为例,分析了高频变压器分布参数对逆变电源性能的影响,并建立了考虑变压器分布参数的变压器模型。通过对一次试验事故的分析,以及对逆变电源分别接电阻负载和高频变压器负载时其输出端的波形的对比,阐述了分布参数对逆变电源性能的影响。最后提出了减小高频变压器分布参数的措施。
Taking the 20 kHz high frequency transformer used in ESP power supply for example,the influence of distribution parameters of the transformer on characteristic of power inverter is analyzed.In view of distribution parameters of the transformer,a transformer model is established.Through the test fault analysis,and the comparison of the different wave forms of the output port when a resistor load and a high frequency transformer load are connected to the power inverter separately, the influence of distribution parameters on characteristics of power inverter is elaborated.At last some measures which can diminish distribution parameters is put forward.
