Abstract :
A new switching method, called the simple partial switching (SPS) method, is proposed for a single-phase AC to DC power converter. The control device switches once in every half cycle of an AC commercial power source by this SPS method. The optimal switching timing is decided by the input power factor and by the odd order harmonic estimation function of the input current. The estimation function is defined as the harmonics ratio compared with the IEC standard concerning the absolute value.<>
