Japanese Patent JP6883729
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To optimize a protection operation of a DC/DC conversion unit.SOLUTION: Electrical equipment comprises a plurality of solar battery strings 1, and a DC/DC conversion circuit 6 for stepping up a DC power, and is configured to output an output of the DC/DC conversion circuit 6 to single DC lines 23a and 23b and to make the output of the DC/DC conversion circuit 6 outputted to the DC lines be used for conversion into an AC power. In a case where at least any one input information of a plurality of electrical input information at the solar battery string side of the DC/DC conversion circuit 6 becomes larger than a value preliminarily defined for each input information, the electrical equipment stops the step-up operation of the DC/DC conversion circuit 6, and in a case where at least any one output information of a plurality of electrical output information resulting from the output to the DC lines of the DC/DC conversion circuit 6 becomes larger than a value preliminarily defined for each output information, the electrical equipment stops the step-up operations of all DC/DC conversion circuits 6.SELECTED DRAWING: Figure 1
