Method for operating final state transistor for controlling injector in combustion engine, involves providing voltage for switching final state transistor by bootstrap-switching part with bootstrap-condenser

摘要

The method involves providing a voltage for switching a final state transistor (10) by a bootstrap-switching part (150) with a bootstrap-condenser (151). Another voltage is applied as charging voltage for the bootstrap-condenser. The latter voltage serves as the bootstrap-switching part in the combustion engine for supplying other components. An independent claim is also included for a circuit for operating a final state transistor for controlling an injector in a combustion engine.
