In the track forming method of optical component technology, in order to achieve ultra-precision grinding, using online electrolytic dressing grinding wheel technology. For this reason, a high-frequency pulsed power source was developed. The developed high-frequency pulsed power source was used to electrolytically trim the metal bonded diamond wheel. High-frequency power from the main circuit, interface circuit and control circuit. The main circuit is to provide the working current path, the control circuit uses a single-chip control technology, the interface circuit to achieve A / D conversion and drive voltage amplification level. The tested power supply voltage is 0 ~ 90V, the pulse frequency is adjustable in the range of 4 ~ 500Hz, and the average current is up to 15A. The power of the technical indicators, have reached the design requirements.
