Abstract: The converter circuit has switches (S1,S2)to sample a DC voltage (U1) to generate a chopper voltage (U3). The switching time is determined by a controller (5) providing a dead band time. The voltage is applied to a resonator circuit having a capacitor(Cr)and inductance (Lr) coupled to the rectifier (7). The switching operation is dependent upon a threshold value comparison.

Abstract: Conventional transformers with fractional turns have pre-manufactured cores usually with a complicated structure. According to the present invention, a method is provided of manufacturing a planar transformer where a ferrite polymer compound is laminated to a PCB for forming the core of the transformer. Advantageously, this may allow for the provision of a cheap and robust transformer.

Abstract: Resonant gate driver circuits provide for an efficient switching of, for example, a MOSFET. However, often an operation of the resonant gate driver circuit does not allow for an application where high switching frequencies are required. According to the present invention, a pre-charging of the inductor of the resonant gate drive circuit is performed. This allows for a highly energy efficient and fast operation of the MOSFET.

Abstract: A converter includes circuit elements for chopping a DC voltage, in which switch-on phases of the circuit elements are alternating. A circuit assembly with resonant elements is used for processing the chopped DC voltage and for producing an output voltage. The voltage present at one of the circuit elements is compared with a threshold in a dead time phase before the circuit element is switched on. The comparison result is used to determine whether an inductive or capacitive converter load is present. Alternatively, a differential quotient of the voltage present at one of the circuit elements during the dead time phase is used to determine whether an inductive or capacitive converter load is present.

Abstract: The method involves generating a control signal dependent at least on an input voltage (Uin) applied to a voltage regulator (2) and on a specific reference value (Vref) for the voltage regulator and regulating the supply voltage (UO) for direct voltage source (1) depending on the control signal. The reference value is a minimum demand value for the necessary input voltage for the voltage regulator. AN Independent claim is also included for the following: a circuit arrangement for regulating a current supply for current loads with a low supply voltage.

Abstract: The mains supply device has an active mains network filter (1) without galvanic separation, for providing a constant DC voltage from the mains network voltage, its output fed to a DC voltage converter (4) with galvanic separation between the constant DC voltage and the voltage converter outputs (6,7). A regulator (5) provides regulation of the reference voltage provided at one voltage converter output, the second voltage converter output coupled to a voltage setting device (11).
