| Abstract: | Upon the study of power supply for high frequency group pulse electrochemical machining, we found that IGBT, the key component of power supply, will arise reverse spike voltage while being shut off, and the proper control will be crucial to raising the precision of electrochemical machining and the products surface quality, aiming at this study, we have given the mathematical model of reverse spike voltage. This paper emphatically introduces this mathematical model and expounds the effect of giving this mathematical model on checking the reverse spike voltage. |
