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.
