    • Frequency converters for converting electrical energy, in particular for a vehicle electrical system, are proposed which have individual partial frequency converters and include at least one half bridge, as a result of which there are at least one high-side switch and one low-side switch with a predeterminable number of switches. The high-side switch and low-side switch have a common connection that is connected to means that produce the electrical energy. Parallel to the half bridge, there is an intermediary circuit capacitor whose capacitance should be as low as possible. To this end, the switches of the half bridge are triggered offset from one another so that the current to be supplied by the intermediary circuit capacitor remains as low as possible. Various possibilities are disclosed for the arrangement of the chokes of the frequency converter.
    • 提出了用于转换电能的变频器,特别是用于车辆电气系统的变频器,其具有单独的部分变频器并且包括至少一个半桥,因此至少有一个高侧开关和一个低侧 用可预定数量的开关切换。 高侧开关和低侧开关具有连接到产生电能的装置的公共连接。 与半桥平行,有一个中间电路电容,其电容应尽可能的低。 为此,半桥的开关被相互触发偏移,使得由中间电路电容器提供的电流保持尽可能低。 公开了用于频率转换器的扼流圈的布置的各种可能性。

    • A protective circuit for protecting an electronic circuit from transient excess voltages, in particular, a series connection of at least two voltage-limiting circuit components being provided between a first connection terminal and a second connection terminal of an input of the protective circuit, each of the two voltage-limiting circuit components having at least one semiconductor element. At least one output terminal is provided at an output for connecting the electronic circuit to be protected to the protective circuit, the output terminal being connected to a circuit node disposed between the two voltage-limiting circuit components.
