Circuit arrangement of an electronically controlled ignition coil

摘要

The pulses of a frequency generator (1) are switched on and off in a driver (2) with the rhythm of a control voltage. The driver (2) controls a power circuit breaker (3) and said breaker feeds the primary winding of a high-voltage transformer (4). As a result, the ignition time is set with a high degree of reproducibility and fluctuates at maximum by the time interval between two successive pulses of the frequency generator. The invention is suitable for the ignition of internal combustion engines. <IMAGE>
