A LINEAR BIPOLAR CURRENT REGULATED DC POWER SUPPLY FOR INDUCTIVE LOADS.

摘要

This invention relates to a linear bipolar current regulated DC power supply for inductive loads comprising a bipolar source of input signal (1) connected to an error amplifier (2) characterized in that said amplifier connected to a bipolar output stage (3) through an integrator (2a) comprising resistance R6 and capacitor C2 to decide the output ramp rate such as herein described, the output of the bipolar output stage connected to a load (4) through a shunt (5), an output filter (4a) connected across the output of the power supply, a feedback circuit (6) connected between the output of the power supply and the input of the error amplifier and the input of the integrator, a zero ampere start (7) circuit being connected across the integrator capacitor.
