Abstract

PURPOSE: To perform current control excellent in the stability, by performing current control through the use of the detection signal across the resistor provided in the current path in matching with the current conduction path by the stored energy of load with the power supply path from the power supply to the load.
CONSTITUTION: The current to the load L is grounded via the power supply E1, transistor TrQ11, load L, TrQ12, and resistor R0 to form the closed circuit consisting of the diode D14, load L, TrQ12, resistor R0, diode D14, and load L to discharge the stored energy of the load L. Current control is made with the detection signal across the resistor R0 in matching the power supply path from the power supply to the load with the power conduction path by the stored energy of the load. Thus, current control excellent in the stability can be made.
