Title:
METHOD AND APPARATUS FOR DRIVING LOAD
Document Type and Number:
Japanese Patent JPH06325655
Kind Code:
A
Abstract:
PURPOSE: To reduce magnetic noise, coming out of and entering a control unit. CONSTITUTION: A load 100 is driven, and a load current is allowed to flow or shielded by an output means 110 having a switching means 140. Accordingly, a drive signal A is impressed to an output means, via a joining line 153 by means of a control unit 120. Individual switching pulse is outputted from the control unit 120 as a drive signal, and the position of the switching means is changed by each switching pulse. Since the switching pulse has short effective period, no signal level appears during a no-pulse period of time between respective switching pulses, so that the noise radiation can be reduced.
