Abstract
The utility model provides an intelligent load balancing apparatus. The apparatus comprises an intelligent controller, an input line, an output first bus, an output second bus, an output third bus, a first bus load detection module, a second bus load detection module, a third bus load detection module, a three-phase A-phase power-off conversion module, a three-phase B-phase power-off conversion module and a three-phase C-phase power-off conversion module. By additionally arranging a three-phase single-phase power-off conversion module on each output bus, the apparatus can make each bus independently controlled according to a real load on the bus. In this way, a certain output bus is powered in a three-phase way while other buses are powered in a single-phase way or even powered off. Meanwhile, when each output bus is in a single-phase state, the outputs are respectively an A-phase output, a B-phase output and a C-phase output. Therefore, a relatively balanced state can be kept among the phases.
