摘要： The invention relates to a voltage supply device for a load, in particular for a network, having an energy store that can be connected to connection terminals and a voltage transformer comprising at least one electronic switch. According to the invention, means for reverse polarity protection are in contact with the connection terminals and are designed to convert voltage delivered from the energy store into control voltage for active activation of the electronic switch when the polarity of said voltage is reversed.

摘要： In a control device (28) for the voltage-absent switching of at least one switching element (18-24) of a voltage converter (10), a detection element (30) detects a resonance voltage between the switching element (18-24) and the transformer unit (14). A control unit (34) generates a control signal for the switching element (18-24) as a function of a value of the detected resonance voltage and outputs the control signal to the switching element (18-24). A ZVS path in the control unit switches the switching element at the right time. A bypass path ensures a continuous switching of the switching element if the resonance signal fails to be emitted.
