Abstract

The invention discloses an automobile generator system. The automobile generator system comprises a generator, a battery, a rectifier circuit, a filter circuit and a regulator for controlling an excitation current in the generator; the generator comprises a stator coil fixed on an engine, and a rotor coil connected to an engine crankshaft; an input end of the rectifier circuit is connected to thestator coil, and an output end of the rectifier circuit is connected to two poles of the battery; the filter circuit and the rectifier circuit are connected in parallel; one end of the rotor coil is connected to an F end of the regulator, and at the other end of the rotor coil is connected to a cathode of the battery. The invention also discloses a starting method of an automobile generator system. The invention can effectively prevent the generator from consuming the starting torque of the starter when the engine is started, and can improve the stability of the output voltage of the generator.

Description

technical field [0001] The invention relates to the technical field of automobile generators, more specifically, it relates to an automobile generator system and a starting method. Background technique [0002] At present, the generator on the car will generate electricity immediately when the engine is started, which will consume the starting torque of the starter and reduce the engine speed, which is not conducive to the ignition and starting of the engine. Moreover, there are voltage instability and many voltage pulsation components during the power generation process. Contents of the invention [0003] The technical problem to be solved by the present invention is to address the above-mentioned shortcomings of the prior art. The first purpose of the present invention is to provide a motor that can effectively prevent the generator from consuming the starting torque of the starter when the engine is started, and can improve the stability of the output voltage of the gene...
