Abstract

The invention discloses an SRM system based on a function integrated converter, and the system is suitable for a plug-in hybrid vehicle driven by an SRM. ON / OFF of switch tubes of a front-end circuit is controlled to realize multiple function and operation modes; in a generator power supply model, the winding voltage is improved by a battery pack; in a battery power supply model, the winding voltage is improved by a capacitor; and multi-level power supply is realized, and further winding excitation and demagnetization are accelerated. Due to the multi-level mode, the torque output capability of the motor is improved obviously. In the electric and braking process, the battery pack can realize charging via multiplexing of windings and control of the converter; and when the vehicle is static, the battery pack can be charged flexibly via an external power supply, and extra charging equipment is not needed. The switch tubes in the converter is controlled to realize energy conversion among the generator, the battery pack, the external power supply and the motor flexibly.

Description

technical field [0001] The invention belongs to the technical field of motors, and in particular relates to a switched reluctance motor system based on a function-integrated converter. Background technique [0002] In recent years, with the rapid consumption of non-renewable energy and the aggravation of urban air pollution, electric vehicles and hybrid vehicles have gradually become the research hotspots of scholars at home and abroad. The emission of electric vehicles is lower than that of traditional internal combustion engine vehicles, and it is more environmentally friendly and energy-saving. However, the battery life of electric vehicles has always been a difficult problem for scholars. At present, hybrid and plug-in hybrid vehicles are extremely important as intermediate transition products between electric vehicles and internal combustion engine vehicles. As a driving motor for hybrid electric vehicles, permanent magnet synchronous motors are now a common choice. H...
