Patent number: 6252785Abstract: A device for operating inverters according to the present invention can operate a plurality of inverters for converting DC output from a DC source such as a solar cell to AC output efficiently without relying on a particular inverter. The plurality of inverters are connected to the DC source through switches. DC output from a DC source is measured by a measuring device to determine the number of inverters to be operated on a basis of the output result from the measuring device. The inverters to be added or cut off are determined among the plurality of inverters at random on a basis of the random number and switches of the determined inverters are turned ON or OFF in order to select inverters to be operated.Type: GrantFiled: October 19, 2000Date of Patent: June 26, 2001Assignee: Sanyo Electric Co., Ltd.Inventors: Ryuzo Hagihara, Kenji Uchihashi, Takeo Ishida
