摘　　要：通过对脉冲变压器原副边回路参数、绕组结构、铁心材料的优化设计,实现了小尺寸变压器对大电流三电极开关的触发。变压器空载输出可达40kV,增加中间储能环节后,在大电流触发管的触发极可产生百A数量级的触发电流,可以实现触发管在较低的欠压比下稳定触发。通过对脉冲变压器绝缘结构的优化设计,确保了脉冲变压器在与触发管配合过程中可以承受其输出电缆折返射造成的过电压与反灌电流。By optimizing the parameters of primary and secondary windings,winding structure and core material,a small size transformer with multiple primary windings for triggering the trigatron is realized.The transformer can output 40 kV in unloaded condition and can afford hundreds of amperes current with an intermediate energy storage capacitor to trigger the switch under low voltage ratio.With the insulation structure being improved,the transformer can withstand any possible over-voltage or back feed current caused by the reflection of the output cables.
