Latest Patents
Stefan Umbricht holds a patent for a "Method for protecting a high-performance power converter." This invention involves a method and apparatus designed to safeguard a high-performance power converter. The converter includes a mains power converter that transforms alternating voltage from a mains power supply into direct voltage. This direct voltage is then supplied to an intermediate direct voltage circuit, which is equipped with an intermediate circuit capacitor. The system also features a second power converter that converts the direct voltage back into alternating voltage. Each of these converters is structured as a bridge circuit, containing pairs of Insulated Gate Bipolar Transistors (IGBTs) arranged in bridge arms. The innovative protection mechanism limits destruction by specifically switching through other bridge arms in the event of a destructive discharge of the intermediate circuit capacitor.
