Patent number: 11108320Abstract: An input voltage is converted into a higher output voltage by several voltage stages each having a series circuit with a rectifier diode, a charging capacitor, and a switchable first semiconductor switch. Each voltage stage has a switchable second semiconductor switch is connected in parallel with the rectifier diode and the charging capacitor. The rectifier diodes of adjacent voltage stages are connected in series. First, the first semiconductor switches are closed and the second semiconductor switches are opened, to charge the charging capacitors by the input voltage. Then, the first semiconductor switches are opened and the second semiconductor switches are closed, so that the individual voltages produced on the charging capacitors add up along the series-connected rectifier diodes to produce the output voltage.Type: GrantFiled: August 14, 2019Date of Patent: August 31, 2021Assignee: Ellenberger & Poensgen GmbHInventors: Dirk Boesche, Ernst-Dieter Wilkening

Patent number: 10637457Abstract: A method for controlling an electronic semiconductor switch connected in a load current circuit, the semiconductor switch being connected between an input terminal routed to a source and an output terminal of the load current circuit routed to a load. A control circuit is connected to a supply voltage and has a bridge circuit connected on the primary side to a transformer and to the supply voltage. A load circuit is connected to the transformer on the secondary side, the load circuit having a driver circuit for the semiconductor switch. A threshold value signal is routed to the bridge circuit on the control side. The bridge circuit generates a primary signal which is transmitted as a secondary signal to the load circuit that is galvanically isolated from the control circuit, and wherein the secondary signal is fed to the driver circuit, which generates a drive signal for the semiconductor switch.Type: GrantFiled: January 28, 2019Date of Patent: April 28, 2020Assignee: Ellenberger & Poensgen GmbHInventors: Dirk Boesche, Ernst-Dieter Wilkening

Patent number: 10607792Abstract: A disconnecting device for interrupting a direct current between a direct current source and an electric apparatus, having a current-conducting mechanical switch, a power electronics unit connected thereto, and an energy store which is charged by an arcing voltage generated on the switch by an arc as the switch is being disconnected. A pulse generator that is connected to the energy store triggers at least one semiconductor switch of the power electronics unit in such a way that the power electronics unit short-circuits the switch and the arc is extinguished.Type: GrantFiled: April 24, 2017Date of Patent: March 31, 2020Assignee: Ellenberger & Poensgen GmbHInventors: Ernst-Dieter Wilkening, Hendrik-Christian Koepf, Dirk Boesche
