Abstract
PURPOSE: To exercise constant current control while exerting no evil influence upon a power reception system by controlling adequately an applied DC voltage until the electric current of a DC circuit reaches a target current value.
CONSTITUTION: Thyristor 3 connected to the secondary side of transformer 2 and rectifier 3' connected to power reception system 1 are connected in series and constant current is supplied to DC circuit load 4. Then, comparing circuit 109 compares current I of the DC circuit with DC current target value I0 to detect when I=I0 and generates an output to set memory circuit 112. Then when I<I0, ignition phase angle (α0) is set by the output of circuit 112 and a constant DC voltage determined by an AC voltage applied to thyristor 3 is developed. When I=I0, circuit 112 is set to establish a voltage feedback system and excellent constant voltage characteristics that hold the DC current constant can be obtained. As a result, the constant current control can be exercised without exerting any evil influence on the power reception system.
