The application for the patent was published on June 26, 2026, under issue no. 26/2026.
Abstract: In an electronic system such as an electric vehicle, damaging overvoltage may be generated very quickly without warning, requiring a rapid response to protect the system. In some embodiments herein, an electronic system may be protected from overvoltage using a hardware-based protection circuit. The protection circuit may include a dissipation resistor, a switch for connecting the resistor to a bus of the electronic system, and a hardware control circuit configured to monitor a bus voltage magnitude of the bus. If the control circuit detects that the bus voltage magnitude is greater than an overvoltage threshold, it may cause the switch to connect the resistor to the bus to dissipate power in the bus. Then, after a minimum time has elapsed, if the bus voltage magnitude has dropped below the overvoltage threshold, the hardware control circuit may cause the switch to disconnect the resistor from the bus.
