INDUSTRY FREQUENCY SINE-WAVE CURRENT STABILIZED DEVICE OF LOW VOLTAGE HEAVY ALTERNATING CURRENT

The present invention is applicable for heating test, special performance test and others fiels wherein stabilized current being needed. Its wave form distortion of the output current is less than 5% with allowable loading resistance variation range 400%, accuracy of stability about 1%, which the current output is varied from 0 to 10 thousands amps and the voltage output from 0 to 10 volts. A stable non-linear magnetic component is used for current regulator link and close loop control system for filter link with short dynamic response time. The common inductive voltage regulator may be used as the power supply of the invention.
