PROBLEM TO BE SOLVED: To provide an inverter apparatus which performs operation of low vibration and low noise, in an inverter apparatus which is used for a brushless motor, a reluctance motor and an induction motor. SOLUTION: This inverter apparatus performs motor operation with and optimum trapezoidal wave voltage waveform or an optimum pseudo-sine wave voltage waveform, by analyzing time high harmonic components by a Fourier series of which the components are contained in a trapezoidal wave voltage or a pseudo-sine wave voltage, where the rising part and the trailing part of a trapezoidal wave are sinusoidal. Thereby the inverter apparatus which performs motor operation of low vibration and low noise can be obtained. |
