    • 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.
    • 根据本发明的用于操作逆变器的装置可以操作多个反相器,用于将来自诸如太阳能电池的DC源的DC输出有效地转换成AC输出,而不依赖于特定的反相器。 多个逆变器通过开关连接到DC源。 来自直流电源的直流输出由测量装置测量,以根据测量装置的输出结果来确定要操作的逆变器的数量。 基于随机数,随机地在多个逆变器之间确定要添加或切断的反相器,并且将所确定的反相器的开关导通或关闭以选择要被操作的反相器。
