Three-phase unified, electric energy quality controller, without isolation link |
Abstract： |
A controller providing identical electric energy quality for three phase without isolation is composed of three identical single- phase controller as each controller being formed by parallel unit including a contravariant bridge prepared by two switching tubes and a filtering inductance, series unit including contravariant bridge prepared by two switching tubes and a filter prepared by capacity and inductance, energy storing unit including two sets of DC capacities. It features that lead wire between two sets of DC capacities is used as common connection wire of series and parallel two units to electric network. |
