  • Filtering reactor stage and variable-frequency driving system using the same
    Patent number: 8994305
    Abstract: A filtering reactor stage and a variable-frequency driving system utilizing the same are provided. The system includes a rectifier input stage, an inverter output stage and a filter reactor stage. The filter reactor stage is coupled between the rectifier input stage and the inverter output stage. The filter reactor stage includes a magnetic core module, a first winding set, a second winding set and a third winding set. The magnetic core module includes a middle pillar and two side pillars. The first second winding sets are wound around two side pillars respectively. The first winding second winding sets are coupled to a first DC (Direct Current) bridge between the rectifier input stage and the inverter output stage. The third winding set is wound around the middle pillar and coupled to a second DC bridge between the rectifier input stage and the inverter output stage.
