摘要： An inverter includes a direct current-alternating current (DC-AC) conversion circuit and a filter circuit, where the filter circuit is connected to an alternating current side of the DC-AC conversion circuit. The filter circuit includes an integrated inductor. The integrated inductor includes a common mode magnetic core, a differential mode magnetic core, and at least two windings. The differential mode magnetic core includes a second magnetic core and a third magnetic core. The common mode magnetic core, the second magnetic core, and the third magnetic core are stacked in sequence. Each winding is located between the third magnetic core and the second magnetic core and is wound on the common mode magnetic core and the second magnetic core. The at least two windings are spaced by the third magnetic core. Set as such, a product volume can be reduced while common mode interference and differential mode interference are suppressed.
