ABSTRACT:
Power factor correction circuit includes an input having a first and second connecting terminal, a first switching element with a control electrode coupled to a current source, a reference electrode coupled to a reference potential and a working electrode, an inductive resistor coupled between the working electrode of the first switching element and the first connecting terminal. The circuit also includes an output having a first and second output terminal, a first diode coupled between the working electrode and the first terminal of the output, a second switching element with a control electrode, a reference electrode coupled to the reference potential and a working electrode, a first capacitor coupled between the control electrode of the second switching element and the working electrode of the first switching element, and a first ohmic resistance coupled between the first connecting terminal of the output and the control electrode of the second switching element.
