Abstract
An assembly includes an insulated gate bipolar transistor (IGBT), a gate driver and a short-circuit protection circuit. The gate driver is adapted to supply voltage to a gate terminal of the IGBT. The short-circuit protection circuit includes an IGBT short-circuit detector for determining whether the IGBT is short-circuited, and a supply voltage regulator for regulating the supply voltage in response to the IGBT short-circuit detector determining that the IGBT is short-circuited.
