68. A Study of a DC Power Supply System Using a Special Winding Structure Transformer

Abstract

In this paper, we investigated whether it is possible to continue operating a DC load when an AC power supply is connected to the secondary-side AC output of the proposed converter as a simulation of a PCS with stand-alone operation function that is capable of outputting three-phase AC voltage. As a result, it was found that by connecting a three-phase power supply to the secondary AC output of the proposed converter, it is possible to continue operation of the DC load even if the primary power supply is lost.
