脉冲变压器是高频电火花穿孔机的一个重要元件,脉冲功率输出的大小与它的匝比有很大的关系。过去我们不懂“优选法”,只好用一些经验数据逐点调试,花费了三个月时间,用了大量的导线和绝缘材料,也未能取得最佳的匝比。这次我们采用了“优选 Pulse transformer is an important component of high frequency electric discharge machine, the size of pulse power output has a great relationship with its turns ratio. In the past, we did not understand the “preferred law” and had to go through the debugging on a point-by-point basis with some empirical data. It took three months, using a large amount of wire and insulating material, and failed to achieve the optimal turn ratio. This time we adopted "preferred
