Design of Dual DC Regulated Power Supply Based on MCU dsPIC30F3011

Abstract:

Traditional dual DC power supply used most of the linear power, which is lack of self-protection function, a high failure rate and the maintenance workload. To introduce a dual DC regulated power supply based on MCU design, the main circuit design using diodes to complete AC/DC conversion, and then through IGBT chopper adjustment, to achieve the DC/DC conversion outputs DC voltage. The control circuit uses dsPIC30F3011 as core, in accordance with the time optimal and PID control to achieve PWM regulation. Experiments results show that the design circuit has failed to self-protection and LCD display, in order to accurately and quickly repair the fault.
