Abstract
A motor driving device and an air conditioner are capable of increasing the efficiency in a low speed region in which a motor performs low speed rotation. The motor driving device that is a motor driving device for driving a motor including stator windings, includes: a connection switching unit that switches connection condition of the stator windings to either of first connection condition and second connection condition different from the first connection condition; and an inverter that converts a DC voltage into AC drive voltages and supplies the AC drive voltages to the stator windings. The inverter includes MOS transistors as switching elements.
