Abstract
A device for driving a plurality of motors and an electric apparatus having the same is disclosed. The device includes an inverter connected to a DC terminal, a multi-phase motor connected to the inverter, a single-phase motor serially connected to the multi-phase motor, and a first capacitor and a second capacitor connected in series between a first end and a second end of the DC terminal, wherein the single-phase motor is connected to the multi-phase motor, and a node between the first capacitor and the second capacitor. Accordingly, a plurality of motors serially connected with each other can be driven by using a single inverter.
