Circuit arrangement and method for controlling an inductive load

摘要

A circuit configuration controls an inductive consumer, especially protecting the consumer from being accidentally turned on. The circuit configuration contains a free-wheeling circuit for reducing energy stored in the consumer. In order to prevent the consumer from being accidentally turned on when a grounding wire between an energy store and the circuit configuration is interrupted, the free-wheeling circuit is interrupted after a given period of time once the consumer has been turned off such that the consumer is prevented from being charged by a current flowing from the positive pole of the energy store via the electronics of the circuit configuration and the free-wheeling circuit.
