Electronic Power Steering System

Electronic Power Steering System

EPS systems are finding widespread use in automobiles to improve mileage. Here are block diagrams of EPS systems that use power MOSFETs for motor drivers, power supply and motor relay applications in EPS systems.

I sistemi EPS sono sempre più diffusi nel settore automobilistico, per migliorare i consumi. Di seguito sono mostrati dei diagrammi a blocchi di sistemi EPS che utilizzano MOSFET di potenza per applicazioni di azionamento motori, alimentazione e releé motori nei sistemi EPS.
