Abstract (en)
[origin: EP0386431A2] A circuit arrangement for measuring the primary voltage of an ignition coil is proposed which manages without transistors and zener diodes and is thus particularly suitable for implementation in hybrid technology. The circuit provides a possibility for analog evaluation of the primary voltage and outputs the spark firing duration in the form of a digital signal. <IMAGE>
