Abstract
A home appliance includes an inductor to which a bias magnet is applied. The inductor of the home appliance may include a core including an air gap in a first leg, and a coil wound around at least a part of the core such that flux flows through the first leg. An upper magnet is positioned above the air gap in the first leg, and a lower magnet is positioned below the air gap in the first leg. In this regard, a direction of flux by the coil may be opposite to a direction of flux by the upper magnet and the lower magnet.
Claims20
A home appliance comprising:
- a rectifier circuit configured to rectify an alternating current (AC) voltage of an input power source;
- a power circuit in signal communication with the rectifier circuit including an inductor that utilizes a magnet, the power circuit configured to perform power conditioning on the rectified DC voltage;
- and
- a link capacitor connected to the power circuit and configured to smooth the rectified DC voltage,
- wherein the power circuit comprises an inductor, and the inductor comprises
- a core including an air gap in a first leg,
- a coil wound around at least a part of the core such that flux flows through the first leg,
- an upper magnet positioned above the air gap in the first leg, and
- a lower magnet positioned below the air gap in the first leg, wherein a direction of flux by the coil is opposite to a direction of flux by the upper magnet and the lower magnet.
