Abstract
An apparatus for enabling an inverter to switch between modes includes: a first inverter unit; a second inverter unit; a load connected between the first inverter unit and the second inverter unit; a mode switching unit connected between the load and the second inverter unit; and a control unit configured to drive the load in a one-stage inverter mode or a two-stage inverter mode by performing control that turns on or off the mode switching unit. In particular, when an inverter switches between modes, the control unit performs mode switching in accordance with correct mode switching timing synchronization for PWM signal output.
