Abstract :
A new insulated gate bipolar transistor (IGBT) has been developed for automotive ignition system applications. The MGP20-N40CL features a low threshold voltage, an extended safe operating area and integrated protective voltage clamping. The device´s model parameters were entered directly into the IGBT model of the Saber simulator. This model was verified by comparing simulation results with experimental resistive and inductive load switching transients and DC characteristics. An ignition coil and spark plug test set was also characterized, and simulation results match for both normal fire and open secondary conditions. Simulation results are also shown for the critical battery voltage transients of a complete ignition system at engine start-up
