CURRENT CONTROL METHOD OF CONTROL RECTIFIER

摘要

PURPOSE:To exercise current control over a control rectifier suitable for digitization by suppressing the generation of a current beat by using the feedback value of a load current the value of the load current set to the mean period of ignition phase control or a period an integer greater than it. CONSTITUTION:An integrator consists of resistance 12, operational amplifier 13 and capacitor 14 and is supplied with a load current detected by current detector 9. In this case, the load current is given as its feedback value the mean period of ignition phase control or a value an integer greater than it. Consequently, current control over a control rectifier suitable for digitization can be exercised by suppressing the generation of a current beat.
