Abstract
In this paper, the design and implementation of a 12/10 poles 6-phase switched reluctance generator (SRG) drive system for hybrid electric vehicles (HEVs) is investigated. Firstly, the principle of the SRG, its control parameters and operation characteristics are analyzed. Then, according to the requirements of the SRG using as an integrated starter generator for HEVs, an optimized switch angle position with current chopping control method is proposed to regulate the SRG power output. In order to improve the charge performance and extend the service life, the lead-acid battery group uses a two-stage charge mode, which is realized by two digital power regulators of the SRG. After that, an experimental system is set up and the controller's internal circuit is described. At last, the proposed SRG drive system is verified by experimental results.
