Design of Programmable DC Power Supply Based on ARM

Abstract:

This paper designed a DC programmable power-supply system based on ARM Cortex-M3 as the main controller. The main power module is supplied with PAF600 from TDK-lambda. This system uses 12 bit serial high speed chip analog-to-digital conversion from TI (Texas Instruments) and 12 bit parallel high resolution analog-to-digital conversion chip from AD (Analog Devices) for the signal of the power supply system of acquisition and adjustment. The system not only can use the encoder and the keyboard to adjust and control, but also can through the RS-232 interface apply the PC software to send command to do that. The signal of power supply system can realize software over-voltage protection and over-current protection function by high speed DAQ (Data Acquisition) ,the rapid data processing of ARM and the least squares curve fitting. This system runs steadily and reliably and also has high adjusting precision and simple operation. The best is to read these instructions and follow the outline of this text.
