Voltage regulator system of automobile high-power generator

Abstract

The invention discloses a voltage regulator system of an automobile high-power generator. An intelligent high-power voltage regulator with multiple functions and compatible with multiple communication specifications is achieved through a special high-power analog signal interface unit (AMU), an intelligent processing unit (IPU) and a power switch. A circuit of the regulator is composed of an analog interface unit and a parameter-adjustable intelligent control unit special integrated circuit of a high-voltage-resistant high-power switch capable of collecting analog signals of the automobile generator and generating drive control excitation. Interface signals comprise acquired near end and far end output voltage signals, IG signals, generator phase voltage signals, indicating lamp detecting signals and excitation coil detecting signals, a control unit circuit comprises a control core logic generator, an interface connector, an automobile bus connector and an engine control unit (ECU) connector. A traditional integrated circuit process and a modern large-scale logic chip production process can be combined, respective advantages are achieved, and the reliability and programmatic interface capacity of an existing product are improved. According to the voltage regulator system, the compatibility, reliability and production efficiency of the product can be greatly improved.
