A drive device of a compressor, including an inverter circuit formed of a plurality of switching elements, a drive unit that switches the switching elements, a determination unit that, when the compression mechanism restarts, determines whether a pressure difference of the compression mechanism is equal to or above a predetermined value, a restart unit that sets a number of times that the switching elements are switched per unit time during an initial predetermined period when the compression mechanism begins to restart and controls the drive unit, where the restart unit sets the number of times that the switching elements are switched per unit time to be lower when the determination unit determines that the pressure difference is equal to or above the threshold as compared to when the determination unit determines that the pressure difference is less than the threshold.
