| Abstract |
The aim of this paper is to give an overview of the semiconductor solutions for the micro-hybrid automotive systems as based on the technologies existing today. First, the motivation for the micro-hybrid, especially for the belt driven starter alternator, is given, followed by the system overview. Alternator in question is the Lundell type alternator with 3-phase and 6-phase configuration. Both starting of the engine and the high efficiency alternator mode are considered. The application requirements are discussed and mapped directly into semiconductor requirements. Special attention is given to power MOSFETs and the driver circuit performance as components of choice for low voltage automotive networks. System demonstrator based on both 3-phase and 6-phase alternator is presented, together with experimental results. Next point is the investigation of packaging and interconnection options, with quality and reliability of power modules. In the end, a future outlook is given. |
