Abstract (en)
[origin: US6661635B1] An electronic drive control used for controlling a drive coil of a contactor during holding operation with a pulse-width modulation. The interval time for the pulse-width modulation is temporally changed or the pulse-width ratio is continuously changed. The invention may minimize the holding power in the case of high voltages without the occurrence of problems associated with EMC and without reducing the functional reliability.
