Abstract
A motor driving device and an air conditioner including the same are disclosed. The disclosed motor driving device includes a rectifier to rectify input AC power, and a converter to convert the power rectified by the rectifier into DC power. The converter includes an interleaved converter including a first converter and a second converter, which operate in an interleaved manner. The first converter of the interleaved converter includes a first boost converter, and a first resonator including a passive element connected to the first boost converter, to perform resonation. Accordingly, it is possible to reduce switching loss generated upon power conversion.
