POWER SUPPLY METHOD AND APPARATUS FOR RECONGNIZATION OF LOAD SEGMENT

摘要

PURPOSE: A power supply method and apparatus for recognizing a load segment are provided to maximize the efficiency of electric power transfer by selectively supplying power to a segment having a load. CONSTITUTION: A control unit(230) detects whether each line segment is in a load condition or not. A control unit supplied electric power to the line segment. A voltage conversion unit(210) converts AC to DC. A feeding unit(220) supplies electric power to a plurality of line segments.
