Design of Programmable Power Supply Based on CPCI

This paper introduces a design scheme of intelligent power module using PIC24 series MCU. According to the demand of a sort of detection system, this design uses DC-DC chips to accomplish voltage converting, and concentrates on the function of anti-interference, overcurrent protection and power distribution. Besides, this design integrates the CAN (Controller Area Network) bus to finish a cascade of power devices with the host.
