DC-DC CONVERTER CURRENT UNBALANCE DETERMINATION DEVICE FOR MEASURING VOLTAGE DROP OF CONNECTORS WITHOUT RUNNING A DC-DC CONVERTER AND A METHOD THEREOF

摘要

PURPOSE: A DC-DC converter current unbalance determination device and a method thereof are provided to determine whether a converter is saturated or not by only measuring voltage drop of connector.;CONSTITUTION: A voltage measuring unit(10) measures the voltage drop of each connector by powering on an output end of a mass-produced DC-DC converter. A standard resistance calculating unit(20) measures a standard resistance with the measured voltage. A saturation criteria value calculating unit(40) calculates a criteria value of saturation. A saturation determining unit(30) determines the saturation condition of a secondary current of a converter by comparing the criteria value with a standard resistance.;COPYRIGHT KIPO 2013;[Reference numerals] (10) Power measuring unit transmission end DC power supply]; (20) Standard resistance calculating unit; (30) Saturation determining unit; (40) Saturation criteria value calculating unit; (50) Display unit
