December 2013 2005 Thirty-first volume, Twelfth issue High voltage technology High Voltage Engineering Vol. 31, No. 12, Dec. 2005 35 A high power switching power supply control system Gu Liangcui (Department of information engineering, Changchun Institute of Technology, Changchun 130021) Abstract: describes the development process of the high voltage charging power supply Philip control system based on sP89C662 MCU. The system will be charging voltage divider to sampling and converted into frequency signal by optical fiber isolation after conversion into the SCM detected. Application of programmable logic device to increase the flexibility of the system hardware, power down save and LCD display function; resistance interference optical fiber isolation and shielding control system to ensure the working reliability. The charging power supply charging voltage of high precision, convenient operation, stable and reliable operation in the field.
