Abstract

The invention discloses a protection device and method for an IGBT driving power supply in an automobile, and the automobile. The device comprises an input anti-reverse-connection protection circuit and a load short-circuit protection circuit. The input anti-reverse-connection protection circuit is arranged at the input end of the IGBT driving power supply and is used for carrying out input anti-reverse-connection protection processing on the IGBT driving power supply; and the load short-circuit protection circuit is arranged at the output end of the IGBT driving power supply and is used for carrying out output short-circuit protection on the IGBT driving power supply. According to the scheme, the problem of poor safety of a vehicle-mounted power supply can be solved, and the effect of improving the safety of the vehicle-mounted power supply is achieved.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and in particular relates to a protection device, method and automobile for an IGBT drive power supply in an automobile, in particular to a novel input anti-reverse connection protection and output load short-circuit protection circuit for an IGBT drive power supply in an electric vehicle , Method And Car. Background technique [0002] With the development of the new energy electric vehicle industry, the issue of functional safety of automotive electronic equipment has received more and more attention from the industry. For vehicle power supply products, it is necessary to meet the requirements of the reverse polarity test item, and the input anti-reverse connection protection circuit must be designed, because when the power line is reversed, the electronic components and batteries will be broken down due to reverse voltage. Cut off the reverse power supply in time, and even dangerous situat...
