Suppression circuit

Abstract

A suppression circuit, in particular for suppressing the noise of the wiper motor of a motor-vehicle, is provided with at least two capacitors (4, 5), which are situated between one common (1) terminal and two separate terminals (2, 3), and it is provided with pulse limitation. For purposes of pulse limitation, each capacitor has connected to it in parallel the series circuit composed of the cathode-anode path of a diode (6, 7) and of the anode-cathode path of a Zener diode (8). The suppression circuit according to the present invention, in one advantageous application, can be embedded as a suppression module in a suppression device, which is provided in a capacitor enclosure. The capacitor enclosure has three contact terminals, which stand in a fixed spatial relationship to each other, irrespective of the number of suppression components, and it can be block-like or cuboid in shape.
