INDUCTOR EVALUATION SYSTEM USING CURRENT COMPARATOR AND EVALUATING METHOD THEREWITH

摘要

PURPOSE: An inductor evaluation system with a current comparator and evaluating method using the same are provided to accurately evaluate an inductor by applying the rated voltage and the rated current of the inductor with a 60Hz power. CONSTITUTION: An inductor evaluation system with a current comparator includes a reference current transformer(120) and a measurement current transformer(130). A current, which is identical to an applied current to the first side of the reference current transformer, is applied to the first side of the measurement current transformer. A load(125) is serially connected to the second side of the reference current transformer. A resistive unit(140) is parallelly connected to the second side of the measurement current transformer. An inductor(150), which is serially connected to the measurement current transformer, is evaluated with the current comparator.
