Title: Circuit arrangement for controlling an inductive load
Inventor: JOST GUNTER
IPC: H03K17/0814
Filed: 1983-11-11
Abstract: Inductive load 1 is supplied with a high initial current followed by a lower holding current. After initial energisation, control means 10 responsive to current sensor 6 controls SCR 17 and switching device 8 so that once the upper limit of holding current has been reached, 8 turns off and current free wheels via 17 until the lower current limit has been reached, when 8 switches on again.
