  • Patent number: 7218533
    Abstract: In a resonance converter for driving variable loads at first an input signal provided by a switch controlled by control means is converted to an output signal by a transformer. The transformer is dimensioned and connected such that a downward transformation ratio between input signal and output signal is between 5:1 and 100:1 when providing nominal power to the variable load. The switching frequency of the switch is controlled on the basis of a phase shift between a switch current and a load current at variable load and/or variable input voltage, a quantity dependent on the input voltage, as well as a quantity dependent on the output voltage. The inventive resonance converter further enables driving variable loads efficiently with the aid of a transformer.

  • Patent number: 7193293
    Abstract: A semiconductor component, which functions according to the principle of charge carrier compensation, has incompletely ionized dopants that are additionally provided in a semiconductor body of the semiconductor component. When a reverse voltage is applied, the degree of compensation changes as a function of time and the breakdown voltage of the semiconductor component increases in a manner governed by the degree of compensation. The invention furthermore relates to a circuit configuration and to a method for doping a compensation layer according to the invention.

  • Publication number: 20070052061
    Abstract: A semiconductor layer with laterally variable doping, and a method for producing it are disclosed. The trenches here are no longer filled up completely with doped semiconductor material. Instead, a doped balancing layer is deposited in a sense as a lining on the walls of the trenches. The doped balancing layer has a defined layer thickness that remains constant over an entire depth of the trenches. Furthermore, both a dopant concentration and the layer thickness of the balancing layer are adjusted such that a complete charge required for compensation is already contained in the balancing layer. The trenches here can advantageously have an arbitrarily great berm angle. The invention is especially advantageous in a peripheral region of semiconductor components with high depletion voltage strength.

  • Patent number: 7126354
    Abstract: A circuit configuration has a load transistor and a current measuring configuration. A method ascertains a load current through a load transistor. The circuit configuration includes a first and a second current sensor with a current measuring transistor in each case. Each of the current sensors provide a current measurement signal that is fed to an evaluation circuit. The evaluation circuit provides, from the first current measurement signal, a current measurement signal that is dependent on the load current. The load transistor and the current measuring transistors are preferably integrated in a common semiconductor body having a multiplicity of transistor cells of identical construction. The evaluation circuit preferably accounts for the spatial position of the cells of the first and second current measuring transistors in the cell array.

  • Patent number: 7005761
    Abstract: A circuit configuration is used for off-load switching. The circuit configuration can be used as a component in a switch mode power supply, a clocked supply, a voltage regulator, and a lamp switch, wherein the circuit configuration is embodied as an IGBT, especially a field stop IGBT or alternately and additionally as a PT IGBT. A method for using the circuit configuration include three operating modes: in a first operating mode, power for a load is modulated by pulse modulation; in a second operating mode, the power is modulated by changing a switching-on time; and, in a third operating mode, both are implemented.

  • Patent number: RE40352
    Abstract: The invention relates to a switching transistor presenting reduced switching losses. In the switching transistor, output capacitance is very high when drain/source voltages are low. As the drain/source voltage increases, the capacitance falls to such low values that the energy stored in the transistor becomes very low.
