Automobile electronic regulator and operating method thereof

Abstract

The invention discloses an automobile electronic regulator and an operating method thereof, and belongs to the technical field of automobile electronics. The automobile electronic regulator comprisesan electronic regulating circuit which consists of an ASIC chip, a power tube and an auxiliary electronic component; the electronic regulating circuit is mounted on a ceramic-based thick film circuitboard; the ASIC chip is an ANC8001 type special multifunctional automobile voltage regulator chip; the power tube is an IGBT power tube; an aluminium profile heat dissipation sheet is glued below theceramic-based thick film circuit board; the ceramic-based thick film circuit board is glued on the aluminium profile heat dissipation sheet through heat dissipation glue; and the surface of the aluminium profile heat dissipation sheet is statically coated with a graphene coated film. The IGBT power tube is initially adopted for improving the current capacity of the power tube; by matching the overload protection function and cooling operation method of the ASIC chip, the automobile electronic regulator is protected, and the problem of heat dissipation is solved; and by virtue of the aluminiumprofile heat dissipation sheet and the graphene coated film, the heat dissipation capability of automobile electronic regulator is improved, and safe and reliable regulation of a high-power automobilegenerator can be achieved.

Description

Technical field [0001] The invention relates to the technical field of automotive electronics, in particular to a built-in automotive electronic regulator with an ultra-high power above 5000W for automotive AC generators and a working method thereof. Background technique [0002] Automobile electronic regulator is an important part of automobile alternator. The automobile alternator is driven by the automobile engine, and the output voltage fluctuates with the change of the engine speed. The function of the automobile electronic regulator is to keep the output voltage of the alternator constant. Since the automotive electronic regulator is installed inside the automotive alternator, due to the limitation of the internal space of the alternator and the severe high-temperature environmental conditions, the current automotive electronic regulator can only meet the needs of the automotive alternator below 5000W. With the increase of vehicle-mounted configuration, the power of automo...
