MUMBAI, India, June 26 -- Intellectual Property India has published a patent application (202617066332 A) filed by Robert Bosch Gmbh on May 26, 2026, for Safety Device For Semiconductor Switches Of An Inverter Output Stage.
Inventors include Graf, Marco; and Walter, Janes.
The application for the patent was published on June 19, 2026, under issue no. 25/2026.
Abstract: The invention relates to a safety device (1) for semiconductor switches (4a,5a,4b,5b,4c,5c) of an inverter output stage (2), comprising a plurality of half-bridges (3a,3b,3c), each of which has an HS semiconductor switch (4a,4b,4c) and an LS semiconductor switch (5a,5b,5c). A respective driver circuit (6a,7a,6b,7b,6c,7c) is provided for each semiconductor switch (4a,5a,4b,5b,4c,5c) of the inverter output stage (2), wherein each driver circuit (6a,7a,6b,7b,6c,7c) is configured as a driver circuit (6a,6b,6c) for a corresponding HS semiconductor switch (4a,4b,4c) or as a driver circuit (7a,7b,7c) for a corresponding LS semiconductor switch (5a,5b,5c), and each driver circuit (6a,7a,6b,7b,6c,7c) has a safety logic (10a,11a,10b,11b,10c,11c) which is designed so that after a safety state is activated, the safety logic actuates the corresponding semiconductor switch (4a,5a,4b,5b,4c,5c) according to a programmed safety configuration such that the inverter output stage (2) assumes the safety state.
