漆包线耐电晕试验用脉冲电源对电压变化率要求高,现有普通电源难以满足要求。提出一种漆包线耐电晕试验用高速脉冲电源设计。建模分析各元件参数和电路主要参数;选用耐高压的绝缘栅双极型晶体管（insulated gate bipolar transistor,IGBT）以提高H桥输出电压;利用栅极电阻的阻值调节脉冲的上升/下降时间。仿真和实验表明,所设计的高速脉冲电源的电压变化率（dv/dt）为30 k V/us,即输出电压峰峰值3 k V的情况下,电压上升时间和下降时间为100 ns。
摘要(英文)：
The pulse power of enameled wire corona resistance test has a high requirements for voltage build-up rate,and the existing ordinary power supply is difficult to meet the requirements.In order to fill the bill,this paper puts forward a kind of high-speed pulse power supply for corona resistance test. Construct the model to analyze the main parameters and circuit components parameters; Choose high voltage of IGBT in order to improve the H bridge output voltage; Use the grid resistance value to adjust pulse rising/falling time. The simulation and ...
