Abstract
The invention relates to a control unit for a motor vehicle. Said control unit comprises a voltage converter which has an inlet for a direct voltage network. Said voltage converter is designed to generate a direct voltage smaller than an input voltage on the inlet for the direct voltage network and the direct voltage is emitted on the outlet side. According to the invention, the voltage converter comprises an inverter and a transformer which is connected to said inverter. Said voltage converter also comprises an inlet for a discharge signal and is designed to discharge by means of the inverter an intermediate circuit capacitor which is connected to the inlet of the direct voltage network in accordance with the discharge signal, and to reduce a working frequency of the inverter, in particular, compared to the frequency with no discharge signal.
