POWER CONVERSION APPARATUS
First Claim
1. An electrical power conversion apparatus, comprising:
- a plurality of electric power converter units being connected in parallel with one another, and each possessing electric power information indicating a relationship between a value of electric power and efficiency, and attribute information including information of a degree of operating priority being an operating order; and
an electric power sharing regulator for regulating, by responding to demanded electric power, electric power shared by each of the electric power converter units, whereinthe electric power sharing regulator supervises go/no-go determination of electrical power conversion operations of the electric power converter units with reference to the attribute information taken in possession from each of the electric power converter units, and regulates electric power in which each of the electric power converter units shares by utilizing a first electric-power threshold value corresponding to rated efficiency of each of the plurality of electric power converter units, a second electric-power threshold value corresponding to a highest efficiency of each of the plurality of electric power converter units, and a third electric-power threshold value corresponding to allowable efficiency being efficiency to become a reference of each of the plurality of electric power converter units, where the electric-power threshold values are pieces of information related to electric power information in the attribute information.

Abstract
In an electrical power conversion apparatus including DC power sources, electric power converter units, and an electric power sharing regulator for regulating electric power on a basis of individual electric power converter units, when the plurality of electric power converter units connects thereto a plurality of DC power sources on their input sides, and is connected in parallel with one another on their output sides, three threshold values of rated electric power, electric power of the highest efficiency, and electric power of allowable efficiency receive attention from an efficiency characteristic of each of the electric power converter units, and the adjustment of electric power shared by each of the electric power converter units is performed by the electric power sharing regulator so that better efficiency is achieved when the apparatus is viewed in its entirety.
