The image below shows the remains of an IGBT that burned out when overdriving a coil. Keep the on time propely limited to avoid burning up your driver circuit! If you are overdriving your coil, also keep in mind you will also have to make sure that the circuit protection (MOV and ...
Step 7: SCR / Triac Driver Now, the SCR driver. This circuit is very straightforward. However, it requires a source of high voltage. The circuit uses the ignition coil as a pulse transformer, and the output is a single-shot high voltage pulse. ...
Fig. 5.52is ablock diagramschematic drawing illustrating this subsystem. The primary circuit of the coil (depicted as the left portionPof the coil inFig. 5.52) is connected to thebatteryand through a power transistor to ground. For convenience, the collector, emitter, and base are denotedC,E...
