Patent number: 11677311Abstract: In a method for operating a controllable converter with an intermediate circuit capacitor, the control behavior can be improved by transmitting, depending on an intermediate circuit voltage applied to the intermediate circuit capacitor, an additional power component via the controllable converter such that the electric current that is generated by the controllable converter for the additional power component counteracts an oscillation of the intermediate circuit voltage. The additional power component is transmitted by the controllable converter to a connected motor as a pulsating additional torque. Also described is a controllable converter with a control unit for carrying out a method, wherein the controllable converter has semiconductors that can be switched off, and an intermediate circuit capacitor designed as a film-type capacitor.Type: GrantFiled: August 18, 2020Date of Patent: June 13, 2023Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Peter Köllensperger, Stephan Neugebauer

Patent number: 11437987Abstract: An electronic switch has a first, a second and a third connection and is configured to disconnect a current flow between the first and the second connection. An energy source is connected between the first and the third connection, and a regenerative load is connected between the second and the third connection. The electronic switch includes a semiconductor switch capable of switching currents of different polarity. A fuse is connected between the first connection and the semiconductor switch. A first short-circuiter is connected between the input of the semiconductor switch and the third connection, and a second short-circuiter is connected between the output of the semiconductor switch and the third connection. The fuse has a current trigger threshold between a permanently permitted current and a maximally permitted current of the semiconductor switch. An electrical network having such electronic switch and a method for operating an electronic switch are disclosed.Type: GrantFiled: January 22, 2020Date of Patent: September 6, 2022Assignee: Siemens AktiengesellschaftInventor: Peter Köllensperger

Publication number: 20220149727Abstract: A switching device is for coupling a DC voltage branch to a DC voltage bus. The switching device includes a series circuit including a first switching module and a second switching module. A first diode is connected in parallel with the first semiconductor switching element and a second diode is connected in parallel with the second semiconductor switching element. A third semiconductor switching element is connected in parallel with the series circuit. A control device is connected to the first and second semiconductor switching elements, to the bridging semiconductor switching element, to the voltage sensor and to the current sensor. The control device is configured to, upon a first threshold value of the voltage being undershot and current flowing in an exceptional case, switch the bridging semiconductor switching element to the conducting state in order to facilitate a current flow from the DC voltage branch to the DC voltage bus.Type: ApplicationFiled: March 13, 2020Publication date: May 12, 2022Applicant: Siemens AktiengesellschaftInventors: Thomas BECKERT, Peter KOELLENSPERGER, Hauke NANNEN, Hubert SCHIERLING, Dieter WAEGELE
