Modeling and control of vehicles’ permanent magnet generating set

The new vehicle electric system comes up with new requirements for economical, efficient alternator design. A single-phase two-half-wave permanent-magnet (PM) synchronous generator for vehicle applications is designed. Its rotor is made up of a rotor core and several pieces of Nd-Fe-B permanent-magnet steel on the core. The simulation models of the permanent magnet generator and its regulator is presented using a toolbox of Matlab named Simulink. Based on the simulation of key element of the control circuit on different state, the single-phase two-half-wave control circuit for permanent magnet generator is designed The generator and regulator experiment is carried out on test platform. The analysis results demonstrate the effectiveness of the proposed circuit design methodology.
