Abstract (en)
[origin: WO2010124987A1] The invention relates to 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.
