Abstract: The present invention relates to a device for improving the harmonic ratio sent back onto the mains in a rectified power supply including a rectifying bridge and at least one capacitor connected to a first output terminal of the rectifying bridge. Between the second terminal of the capacitor and a second output terminal, a first charge path including a resistor is provided, as well as a second switchable discharge path, associated with means for switching on the discharge path only after the supply voltage has transmitted through a maximum.
