Abstract

PURPOSE:To make the driving circuit function as a constant current circuit against the driving coil of small resistivity and also function as a constant voltage circuit for the restoration-time coil of large resistivity respectively. As a result, an excessive current unnecessary for the driving coil can be avoided.
