Abstract
A circuit for applying a driving voltage to an inductive load for a period of time sufficient to increase the current in the load to a maximum desired level, and for disconnecting the driving voltage for fixed intervals between each application so as to maintain the level of current flow through the inductive load below the maximum desired level so as to permit the application of a high drive voltage without causing excessive heating in the inductor.
