HIGH POWER FACTOR AC TO DC CONVERTER CIRCUIT A high power factor AC to DC converter circuit includes a rectifier circuit coupled to an AC potential source and providing a full-wave rectified pulsating DC potential to a switching regulator circuit with a radio frequency current filter connected in circuit with the rectifier and switching regulator circuits to provide a pulsating DC current in phase with and of at least 50% duration of said pulsating DC potential whereby a power factor of at least 90% is effected. |
