  • Power electronic voltage tranforming apparatus with single-phase power electronic transformers
    Patent number: 10236685
    Abstract: A power electronic voltage transforming apparatus is used in a two-phase to single-phase conversion. The power electronic voltage transforming apparatus is cooperatively used with a three-phase to two-phase transformer to convert the two-phase power output from the three-phase to two-phase transformer into single-phase power. The two-phase to single-phase power electronic voltage transforming apparatus or three-phase to single-phase power electronic voltage transforming apparatus has an input cascade connection structure formed by cascading n converter modules.
