Embodiment Construction

[0010] The present invention will be further described below in conjunction with accompanying drawing:

[0011] The electric vehicle range extender generator three-phase half-wave pulse type voltage stabilization control method is characterized in that: the electric vehicle range extender generator works under the coordinated control of the reference circuit 1, the comparison circuit 2 and the trigger circuit 3, and can be The phase-shift clipping and rectification function of the silicon controlled circuit ensures the stable DC output voltage of the generator;

[0012] When the generator starts to rotate, the reference circuit 1 first detects the output voltage U of the permanent magnet generator, and then compares the output voltage signal U with the target voltage regulation value U set in the reference circuit 1 0 Send to the comparison circuit 2, the comparison circuit 2 compares the output voltage U of the generator and the target voltage regulation value U set in the re...

Abstract

The invention provides a three-phase half-wave pulse type voltage stabilization control method for an electric vehicle range extender generator, and belongs to the technical field of electric vehicle control. The permanent magnet generator used for an electric vehicle works under coordinative control of a reference circuit, a comparison circuit and a triggering circuit, and three silicon controlled rectifiers are connected with three phases of armature windings respectively to form a three-phase half-wave pulse type controllable current rectification and voltage stabilization circuit. Through phase shifting, clipping and rectifying, output voltage of the generator is kept stable; because each silicon controlled rectifier is only connected with one phase of armature winding in series, current distribution is even, the problem that because large-current output elements are connected in parallel, current distribution is uneven is solved, and the reliability of main elements is improved.
