A buck converter is equipped with a switch, a diode, an inductance, a capacitor, an input with a first connection and second connection, and an output with a first connection and second connection. The first connection of the input is connected to the first connection of the output via a series circuit comprised of the switch and the inductance; in particular, the switch is provided on the input side and the inductance is provided on the output side. In addition, the cathode of the diode is connected to the connection between the switch and the inductance while the anode of the diode is connected to the second connection of the input and to the second connection of the output. The capacitor is connected in parallel with the connections of the output. It is possible to trigger the switch by combining a first signal with a second signal and a third signal corresponding to a control variable from the output of the buck converter may be used to adjust the output signal.

Buck converter with demagnetization detection of the inductor

There is provided a resonance transducer including a main bridge linked with an input signal. The resonance transducer includes a transformer assembly across which an output signal can be tapped, a resonance circuit and a control circuit. In this arrangement, the transformer assembly is linked with the main bridge and the resonance circuit, the resonance circuit is further linked with the main bridge and the control circuit, and the control circuit is further linked with the main bridge.

Resonance transducer

A power supply, including a step-up converter, a resonant converter, and control unit. The step-up converter is connected to the resonant converter; the step-up converter and the resonant converter are each connected to the primary control unit.
