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.
