Development of a High Precision and Controllable Power Source Based on Embedded System

ZHAO Bing,ZHOU Jian-zhong,FU Bo,ZOU Tuo-wu College of Hydroelectric and Information Engineering,Huazhong University of Science and Technology,Wuhan 430074China  
To accomplish the testing of secondary equipments in power system a controllable power source based on the embedded system is designed in this paper. It can supply constant voltages and currents with high precision and high power and users can set the waveform parameters and output modes. The power source has been in a pre-operational test and the performance is good. The design of the system fabric the DSP control board the algorithm of waveform generating and the power amplifier are introduced.
