Abstract
A current source capable of generating a current of a first compensation portion for either or both reducing a harmonic current in an air conditioner or improving a fundamental power factor in the air conditioner is provided. If an excess of the current source is larger than a second compensation portion for either or both reducing a harmonic current in a power receiving path of a distribution board or improving a fundamental power factor in the power receiving path of the distribution board, a current obtained through superimposition of a current of a second compensation component and a current of the first compensation component is generated in the current source.
