Abstract
A control circuit of an electric motor includes a filtering device in order to filter high frequencies likely to produce perturbing electromagnetic radiation when the electric motor is driven. To this end, the filtering device includes one or more filtering capacitors branched off from a power bridge driving the electric motor, wherein at least a proportion of the filtering capacitors is of a polymer-hybrid type in order to improve dynamic performance of the filtering device and to reduce its size. A motorized-fan unit for motor vehicles including such a control circuit is also disclosed.
