PURPOSE:To obtain a small-sized low-cost inverter device while maintaining DC voltage with high accuracy. CONSTITUTION:An inverter device is composed of a converter circuit 2 connected to a power-supply transformer 1 to convert AC power into DC power, a DC capacitor 3 smoothing DC voltage generated by the converter circuit 2, an inverter circuit 4 converting DC power fed through the DC capacitor 3 into AC power by the converter circuit 2 and a power converter 6 for controlling voltage fluctuation connected in parallel with the DC capacitor 3. |
