Modeling and Simulation of an Integrated Starter Generator Based on PMSM with SVPWM Strategy for Engine Starting and Battery Charging

Abstract

The modelling and simulation of an integrated starter generator (ISG) system with 48 and 12-volt DC power setup for use in automotive applications is presented in this paper. The ISG system is a key component in these applications, providing both engine starting and battery charging capabilities. A mathematical model of the ISG system is developed using Simulink, and the system is simulated under various conditions with a 48- and 12-volt DC power setup. The results of the simulations are presented and discussed, highlighting the performance and efficiency of the ISG system.
