Publication number: 20210126531Abstract: An input circuit for a power supply includes an input voltage that is converted into an output voltage via periodic switching of a switch between conductive/blocked states, wherein current that charges a capacitance and supplies output voltage flows through an inductor at least during switching of the switch, and is absorbed by an active switch unit when the switch is in the blocked state and is permitted through the switch in the blocked state, upon exceeding a predefined breakdown voltage at the switch, such that during an overvoltage at the input circuit, the switch is switched into the blocked state, and current flow that then occurs is relayable into the inductor and the active switch unit is deactivatable, the switch and inductor being dimensioned such that, during an overvoltage, an “avalanche energy” occurs at the switch, upon which the switch withstands the current flowing through the inductor during the over-voltage.Type: ApplicationFiled: June 17, 2019Publication date: April 29, 2021Inventors: Thomas Rothmayer, Harald Schwelgert

Patent number: 7235956Abstract: A step up switching converter is disclosed. The switching converter comprises a first semiconductor switch arranged in series connection with a storage inductor and a sensor resistor. The control electrode of the first semiconductor switch is connected via a resistor to the input voltage, the resistor constituting the operating resistor of a second semiconductor switch. The voltage drop of the sensor resistor is fed to the control electrode of the second semiconductor switch as an indicator of the current through the storage inductor, and that connection of the storage inductor connected to the first semiconductor switch being connected on the one hand via a rectifier diode to an output capacitor which carries the output voltage, and on the other hand via a series RC element to the control input of the second semiconductor switch.Type: GrantFiled: July 26, 2004Date of Patent: June 26, 2007Assignee: Siemens AG OsterreichInventor: Thomas Rothmayer
