Power Semiconductors for Starter-Alternator Systems

Modern semiconductor devices enable highly efficient conversion of electrical power. Together with the microcontroller, they are the key elements for generation of the alternating currents from the car's DC supply that are necessary to drive high-performance units such as starter-alternators. These allow the combustion engine to crank up in several 100 ms and deliver up to 15 kW of electrical power. Smart driver ICs such as the TLE6280 enable the fast development of the interface between the microcontroller and the power switches. Currents of some 100A can be handled with the new OptiMOS FETs. Their rugged and ultra-low ohmic technology and their innovative packaging concepts, such as Power Modules and Power-Bonded MOSFETs, allow the building of compact and efficient control units.
