The current balance, thermal stability, and switching behavior characteristics of parallel insulated-gate bipolar transistors (IGBTs) are analyzed. The influences of heat sink mounting, lay-out, and the drive circuit are described in order to demonstrate the best way to parallel IGBTs for optimum performance. An example of two paralleled IGBTs in a fully(More)
Among automotive actuators, those equipping power windows, seat and mirror positioning require a quite precise position control, either for easy of usage, either for safety reasons. Noticeable cost reductions can be obtained on such kind of actuators by elimination of Hall effect position sensors. This can be accomplished by sensorless estimating the(More)
Body electronics systems are pervasively spreading all over modern vehicles making cars easy to operate, relieving drivers from several minor tasks and improving safety and comfort. These systems are connected between them and to peripheral control units through networks based on serial protocols. Cost reductions can be accomplished by adopting Power Line(More)
