Modulated active short circuit braking
11760210 · 2023-09-19 · ·

Methods and systems are provided for modulating undesired electric-motor braking. Based upon the detection of an inverter degradation event, one of a first gate driver and a second gate driver (e.g., a high gate driver and a low gate driver, such as for one phase of an inverter) may be asserted in an alternating manner while the other of the first gate driver and a second gate driver is de-asserted, and the first gate driver and second gate driver may then be provided to a power switch circuitry. The alternating assertion of the one of the first gate driver and the second gate driver may be associated with a higher-speed state, and the de-assertion of both the first gate driver and the second gate driver may be associated with a lower-speed state.
