IGBT的汽车点火 APPLICATION NOTE CAR IGNITION WITH IGBTS by M. Melito ABSTRACT IGBTs are used in a variety of switching very fast. However they must have very low applications thanks to their attractive V CE(sat), and be very rugged. Existing characteristics, particularly their peak current technology allows a compromise between capability, ruggedness and simple gate drive switching speed, ruggedness and power requirements. Until recently their use was dissipation. limited to the electrical drive sector, where This paper gives a brief explanation of the they ……
