The Power Electronics & Power Quality Laboratory of Texas A&M University is currently exploring several implementation aspects of digital control of power factor correction (PFC) stage of SMPS. Two low cost digital controllers: TMS320LF2407 and ST52x420 are evaluated for implementing PFC function. Simulation and experimental results are shown to demonstrate PFC control of SMPS to meet IEC 1000-3 harmonic limits.
