Patent number: 11509212Abstract: A switched-mode power supply has a rectifier device, a switching unit which is arranged downstream of the rectifier device, a transmission device which is arranged downstream of the switching unit and a filter device. In order to reduce the sensitivity of the switched-mode power supply to high-energy interferences, it is proposed that the filter device contains a current-compensated choke coil which is connected to a voltage limiter circuit in such a way that in the case of interference signals applied to the choke coil, a damping of the interference signals takes place by way of the voltage limiter circuit.Type: GrantFiled: January 28, 2021Date of Patent: November 22, 2022Assignee: Siemens AktiengesellschaftInventors: Carsten Braun, Joerg Braune

Patent number: 8988844Abstract: A drive circuit for an electromagnetic relay having a relay coil and switch contacts, includes a first switching device between a first coil terminal and a first voltage source, a second switching device between a second coil terminal and a zero potential, and a control device producing a current through the coil closing both switching devices. To provide the shortest possible response time and simple and cost-effective construction, a second voltage source is connected through a third switching device to the first coil terminal. The third switching device is connected in parallel with the first switching device, the second voltage source has a higher voltage level than the first voltage source and the control device produces a current through the coil, initially closing all three switching devices and following expiration of a predefined period, opening the third switching device again and keep the first and second switching devices closed.Type: GrantFiled: December 20, 2010Date of Patent: March 24, 2015Assignee: Siemens AktiengesellschaftInventors: Carsten Braun, Ronald Stempel, Harald Strohmaier
