| Abstract: | It has been proved by trial production of the mode of engine valve that high frequency short pulse electrochemical machining(HSPECM) is the available technical approach to enhance the accuracy of ECM. This paper introduced the specification of the power supply of HSPECM, also the basic diagram and the technical critical problem: the deformation of waveform, the tendency of reverse current, the break down of the transient overvoltage, the over heat damage of the power MOSFET, the rapid short circuit protection, etc. |
