The utility model provides an inductive device, including a columnar magnetic core provided with grooves on side surfaces thereof; a frame assembly including embedding portions adapted to the grooves in shape, the embedding portions being embedded in the grooves; and an inductive coil wound onto the side surfaces of the columnar magnetic core. The inductive device of the utility model has the advantages of saved winding use amount and prolonged service life.

Inductive device

A multi-input power converter includes three bridge arm units connected between a three-phase AC power supply and a positive/negative DC bus. First and second capacitors are connected in series between the positive and negative DC buses with a node connected to a neutral point. Each bridge arm unit includes an inductor and a bidirectional switch unit connected in series with a node connected to a current direction control bridge arm between the positive and negative DC buses. Second ends of bidirectional switch units are connected to the neutral point. In a battery mode, two of the bridge arm units are as battery mounting bridge arms to constitute a DC loop with a rechargeable battery to supply power to the positive and negative DC buses, and the remaining bridge arm unit enables an inductor thereon to alternately connect the positive and negative DC buses to balance a bus capacitance voltage.

The present invention relates to a bracket device for bearing an inductor, an inductor device, and an uninterruptible power supply. The inductor comprises a toroidal magnetic core; and a coil comprising a plurality of wires wound around the toroidal magnetic core. The bracket device comprises: a bracket having a bearing portion adapted to bear the inductor; an insulating pad adapted to be sandwiched between the inductor and the bearing portion of the bracket, the insulating pad having an integrally formed positioning structure capable of being embedded between two adjacent wires of the coil and keeping the toroidal magnetic core fixed; and a fastener adapted to wrap around the toroidal magnetic core and press the toroidal magnetic core together with the insulating pad against the bracket. The bracket device of the present invention is capable of effectively fixing an inductor and allowing it to dissipate heat well.
