PROBLEM TO BE SOLVED: To provide an inverter device which can improve input distortion and also can supply stable output without incurring sharp increase of a switching current. SOLUTION: The series circuit of at least two small capacitance capacitors C1 and C2 smaller in capacitance than a power capacitor EC is connected in parallel with the power capacitor EC, and an AC power source POW is connected through a rectifier circuit to at least one small capacitance capacitor, and also at least one switching means and a load circuit LO are connected to each other through an impedance element, and at least an impedance element is connected through at least one switching means to at least one small capacitance capacitor. |
