Analysis of low frequency harmonics for continuous-conduction-mode boost power-factor correction

The input current harmonics of continuous-conduction-mode boost power-factor correction (CCMPFC) are presented. Input current distortion of single-phase CCMPFC is analysed and harmonic components are mathematically derived. Upper limits of the boost inductance for CCMPFC are also discussed. Design examples of CCMPFC are demonstrated. Experimental recordings verify the analytical derivations.
