The paper proposed a high-precision digital power design plan based on PID algorithm. This solution use DSP and FPGA techeoiogy to accomplish the digdtal PID regulator. Generating PWM wave through the digital PID algorithm to control the chopper and the main drcuit. This design plan will replace the tracIitlenal analog PID regulator and make the circuit easier, more accurate .and more versatile. The test shows that the system basically reached requirement and meet the high accuracy design requirements, and got a expected result through some tests, The system design can be used not only in the power controller, but also in the related field.
