A design method of Dual DC regulated power supply based on micro control unit is intro- duced, the main circuit using the single end fly back converter to realize the DCA)C transformation, and output of DC voltage. The control circuit uses COPSCDR9 single chip as the core, according to the opti- mal time and PID control method to achieve PWM modulation. Practice has proved that this design method has faulted self protection and liquid crystal display function.
