一种用于机动车的控制单元
摘要：
本发明涉及一种用于机动车的控制单元。所述控制单元具有电压转换器，其中，所述电压转换器具有用于直流电网的输入端。所述电压转换器被构造为在输出侧产生比在用于所述直流电网的所述输入端处的输入电压更小的直流电压并且在输出侧输出所述直流电压。依据本发明，所述电压转换器具有逆变器和与所述逆变器连接的变压器。所述电压转换器还具有用于放电信号的输入端并且被构造为根据所述放电信号通过所述逆变器为与用于所述直流电网的所述输入端相连接的中间电路电容器放电并且为此尤其是相较于无放电信号减小所述逆变器的工作频率。
摘要（英）：

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.
