APPARATUS FOR DRIVING LOAD

摘要

PURPOSE: A load driving device is provided to drive a load with large capacity by operating a power device with suitable capacity according to the size change of the load. CONSTITUTION: A load driver(120) drives first to third loads(110) using one among the first and second power devices. A controller(130) controls the current flow of the load driver by controlling the operation of the first and second power devices according to the size change of the one of the first and third loads. The first and third loads are serially connected. The negative pole and the positive pole of the first power device are connected to the left and right sides of the second load. The positive pole and the negative pole of the second power device is connected to the right side of the third load and the left side of the first load.
