Embodiment 1

[0006] Embodiment 1: As shown in Figure 1, the rectifying voltage stabilizer (2) is a bridge-type semi-controlled rectifying and stabilizing circuit composed of 6 bridge arms, and each bridge arm is composed of 1 rectifying diode and 1 thyristor. 6 thyristors V1-V6 are connected with common cathode, and 6 rectifier diodes V7-V12 are connected with common anode. The permanent magnet generator (1) has three-phase windings L1, L2 and L3, each phase winding is independently output, and there is no connection between the windings, that is, the traditional Y-type or Δ-type connection is not used, and each phase winding has two leads There are 6 outgoing wires in total, which are respectively connected to 6 bridge arms. Although the permanent magnet generator (1) is a three-phase permanent magnet synchronous generator, since there is no connection between the windings, each phase winding works independently, which is equivalent to three independent single-phase generators. combinati...

Embodiment 2

[0007] Embodiment 2: The solution consists of two parts, a permanent magnet generator (1) and a rectifier regulator (3), as shown in Figure 2. The rectifier voltage stabilizer (3) also has a 6-arm structure, and its characteristics are: 6 thyristors V19-V24 are connected with a common anode, and 6 rectifier diodes V13-V18 are connected with a common cathode. Other structures, working principles and working processes are basically the same as in "Embodiment 1".

Abstract

This invention relates to a magnet generator used in cars composed of a magnet generator and a commutaing regulator, in which, the magnet generator includes three phases of windings, and each outputs independently without any connection among them, namely, traditional Y or triangle type connection method is not used here, every winding includes two lead out lines corresponding to the combined work with three independent single phase generators, and the energy generated by the generators is used to charge storage battery of a car and supply electric devices after being rectified and regulated.

Description

technical field [0001] The invention is a permanent magnet generator for vehicles, which is suitable for charging and power supplying various electric starting motor vehicles and fixed power. Background technique [0002] At present, silicon rectifier alternators and permanent magnet generators commonly used in automobiles are composed of three-phase synchronous generators and three-phase bridge rectifiers. Most of their windings are Y-connected, and models with higher power also use Δ Type connection, no matter Y type or Δ type connection, use three-phase bridge rectifier for rectification. Chinese patent: ZL01209419.6 provides a permanent magnet generator, the windings of which are neither Y-shaped nor Δ-shaped, but the three-phase windings are independently output. However, its rectifier regulator is a bridge-type fully-controlled rectifier circuit composed of 12 thyristors. The disadvantage is that the structure of the fully-controlled rectifier bridge is very complicat...
