摘要： PROBLEM TO BE SOLVED: To provide a driving device for alternating-current motors wherein a secondary voltage can instantaneously respond to a quick increase in required power without oscillation in control and oscillation does not occur in the secondary voltage under a light load. SOLUTION: The driving device for alternating-current motors includes a power supply 1 that generates direct-current primary power, a DC-DC converter 2 that boosts the primary power generated by the power supply 1, an inverter 4 that converts direct-current secondary power boosted at the DC-DC converter 2 into alternating-current power, an alternating-current motor 5 that is driven by the supply of the alternating-current power converted at the inverter 4, and a first controller 3 that determines a conduction ratio and controls a step-up/down operation of the DC-DC converter 2 according to this conduction ratio. The first controller 3 determines a final conduction ratio Duty0 from the following conduction ratios: a basic conduction ratio Duty1 identified based on PI control or PD control and an additional conduction ratio Duty2 identified according to high load or low load determined based on the primary power generated by the power supply 1.
