Abstract: An energy combiner apparatus is used to convert output of a power supply, and has three output terminals, so that output ports are increased.

Therefore, a thinner cable may be used, so that costs of the cable are reduced. In addition, four cables conventionally required for connecting to the output terminals of the energy combiner apparatus are reduced to three, so that quantity and costs are reduced.
