    • PROBLEM TO BE SOLVED: To provide a load driving unit which can efficiently perform the drive of a load by the power accumulated in a capacitor and the accumulation of regenerative power recovered from the load. SOLUTION: The load driving unit possesses an AC/DC converter 2 which converts AC power given from an external power source 1 into DC power and accumulates it in the capacitor 3 and also regenerates power accumulated in the capacitor 3 into the external power source, and an inverter which drives the load, using the power accummulted in the capacitor 3, and also accumulates the regenerative power obtained from the load into the capacitor 3. Especially, a controller, which controls the operation of the AC/DC converter 2, makes it perform the power supply operation from the external power source 1 while limiting the current when the detected value of DC voltage on the DC side of the converter is smaller than the set value of DC voltage, and makes it perform the power regenerative operation to the external power source 1 while limiting the current when conversely the detected value of the DC voltage is larger than the set value of DC voltage.
