FREE-RUNNING CAPACITIVE DISCHARGE IGNITION SYSTEM WITH SPARK FREQUENCY CONTROL |
摘要 |
An ignition system is provided that marries a free-running discharge circuit with a fast-charging, high voltage converter without resulting in an excessive rate of discharge. To this end, the free-running discharge circuit employs a passive switch embodied either as a spark-gap device or a passive network of semiconductor elements. A feedback circuit detects discharge events at the discharge circuit and, in response thereto, selectively enables and disables the fast-charging converter. A spark rate clock is integrated into the feedback circuit for the purpose of setting the average discharge rate to a predetermined value. |
