ECI ignition system power pack design

N91 ECI ignition system mains unit The ignition must not be switched on withoutr an earth connection to the power pack for the ignition system ECI is order to avoid any damage occurring. The earth connection is achieved over the housing.

Mechanical structure: An aluminium die cast housing with plastic cover. Electrical structure: The DC converter is built discretely out of condensers, coils, transistors etc.. The DC voltages so generated have a load dependent duty cycle of about 10 to 90%, while the frequency is about 20 kHz (180 volts) and 65 kHz (23 volts).

The power pack is fitted with electronic overload protection for the voltages 180 volts and 23 volts. The outputs are switched off if a short-circuit or overload situation arises. They will remain locked out until the ignition is switched on again. Protection of the battery voltage which is looped to the ignition modules takes place on the vehicle side.
