As further preferred, described rectification filtering unit comprises three-phase bridge rectifier and is attached thereto the filter capacitor connect.
As further preferred, stator winding is leg-of-mutton connected mode, the input of the corresponding three-phase bridge rectifier of three-phase difference of stator winding.
As further preferred, described generator adopts compact type large power generator, and specified peak power reaches 5.5KW, and adopts built-in double fans structure, composite excitation technology, possesses the advantages such as efficiency is high, noise is little, long service life.
As further preferred, described adjuster is voltage regulator, and every platform generator, after adjuster process, makes voltage-regulation close.
As further preferred, described voltage regulator comprises voltage sampling circuit, and it is used for detecting battery tension.
