【Abstract】 This article describes a new practical CO2 laser power supply with IGBT as power inversion. The application of the technology of precharge and series output of high voltages enables to meet the requires of high frequency on-off switch for engraving. The power supply is towards small size, high frequency, integration and all-purpose. The result of testing and application of the power shows that it has good ratio of quality versus price, high reliability, and fit for manufacture.更多还原
