Belt-Driven Integrated Starter and Generator Using Planetary Gears for Micro Hybrid Electric Vehicles

This paper presents a 12 V mechanical torque converting belt-driven integrated starter and generator (BSG) system without DC-DC converter. A micro hybrid electric vehicle (micro HEV) typically uses battery with 12/48 bidirectional converter to satisfy its high starting wide operating speed for generating the required power. In contrast, proposed BSG consists of wound field synchronous machine (WFSM), planetary gears, belt-type pulley, which does not require an additional Owing converter, produces in starter-mode 12:1 gear ratio, it operates generator-mode 1:2 ratio target specifications. To verify that meets design specifications, simulations using MATLAB/Simulink 2018b ANSYS electromagnetic 19.0 were performed. Additionally, experimental results this modes Based on analysis cost environment conditions, provides efficient solution issue incurred by micro-HEV requires system.
