Dc -to -ac converter testing arrangement

The utility model provides a dc -to -ac converter testing arrangement, including first transformer and adjustable direct current source, the former limit of first transformer is used for connecting ACelectric network, and the input in adjustable direct current source is connected on vice limit, and the output in adjustable direct current source is used for connecting the dc -to -ac converter thatawaits measuring, still include the second transformer, the second transformer's former limit is used for connecting the interchange side of the dc -to -ac converter that awaits measuring, and vice limit is used for connecting the electric wire netting. The utility model provides a technical scheme, the interchange of the dc -to -ac converter that will await measuring side inserts the electric wire netting or is connected to first transformer through the second transformer, and electric energy feedback after in the time of will testing carries out cyclic utilization to the electric wire netting in to reduce the waste
