Abstract :
A digital signal processor (DSP) implementation of digital control for constant-frequency, discontinuous-conduction-mode boost power-factor-correction converter for universal line-voltage (90-264 V/sub rms/) applications is presented. A step-by-step design procedure based on digital redesign technique is also provided. The performance evaluation of the proposed DSP control is performed on a 400-W prototype. It was shown that the implemented DSP-based control can achieve a power factor higher than 0.99 in the entire line range.
