Problems solved by technology

[0004] Therefore, when desiring to operate the generator, a rectifier 2 and a voltage regulator 3 must be installed. The rectifier 2 and the voltage regulator 3 are produced separately and must have their respective pins, heat sinks and carriers, and then they are packaged into A single product is configured to be used on a generator, so its manufacturing cost is high and power generation efficiency is low

Abstract

The invention discloses a circuit integrated chip for a vehicle generator, comprising a rectifying unit and a voltage regulating unit, wherein the rectifying unit is provided with a metal-oxide-semiconductor field effect transistor (MOSFET), a rectifying power module, a rectifying control circuit, an input end and an output end; the input end is connected to a stator coil of the generator and used for converting alternating current into direct current and outputting the direct current from the output end; the voltage regulating unit is provided with a control circuit and a power module; and the power module of the voltage regulating unit is electrically connected to a rotor coil of the generator so as to regulate the output voltage value of the generator.

Description

technical field [0001] The invention relates to a circuit integrated chip for a vehicle generator, in particular a chip that integrates a rectifier and a voltage regulator, which not only makes it more practical, but also reduces production costs and can effectively improve its reliability. Background technique [0002] Please refer to figure 1 As shown, it is a schematic diagram of the operation of a voltage regulator of a typical automotive alternator. The generator 1 includes a stator coil 11 (stator) and a rotor coil 12 (rotor). However, when the engine drives the rotor coil 12 to rotate, a fluctuating magnetic field will be produced, so that the stator coil 11 will generate an alternating current, and the alternating current will be input into the rectifier diode 2 through the input terminal 22 of a rectifier diode 2, and converted into a direct current. And connect the high-voltage terminal 41 of storage battery by its output terminal 21, and charge storage battery 4,...
