The Digital Control System of Low-power DC/DC Power Supply of HIRFL

One digital control system for DC/DC power supply is designed.Field programmable gate array(FPGA), complex programmable logic device(CPLD) and micro control unit(MCU) are used as the main control elements,and advantages of these elements are full used.State detection,relay control,current quality regulation and CAN bus communication are supported.The experimental results show diat the digital control system has good stability and it can be generally used in other power supplies.
