Abstract: The present disclosure provides an inverter module capable of driving two linear compressors through three upper arm elements and three lower arm elements. To this end, an inverter module according to an embodiment may include an inverter module including a first inverter unit including a first upper arm and a first lower arm; a second inverter unit including a second upper arm, a second lower arm, a third upper arm and a third lower arm; and a controller configured to control the switching operation of the first upper arm and the first lower arm to allow the first inverter unit to drive a first compressor in a half-bridge configuration, and control the switching operation of the second upper arm, the second lower arm, the third upper arm and the third lower arm to allow the second inverter unit to drive a second compressor in a full-bridge configuration during a first operation mode, and control the switching operation of the first upper arm, the first lower arm, the second upper arm, the second lower arm, the third upper arm and the third lower arm to allow the first inverter unit and the second inverter unit to drive the first compressor and the second compressor in a full-bridge configuration during a second operation mode.
