Abstract
A power converting device includes at least power source section providing a pulsation voltage output of a stepped waveform, and a piezo-electric element for shaping output voltage waveform of the power source section substantially into a sinusoidal waveform and boosting and dropping output voltage value of the power source section. A fundamental wave component of the piezo-electric element is transformed by a boosting and dropping element and a filter element to be applied to a load, whereby it is enabled to apply to the load a required voltage of a substantially continuous waveform, without employing any element of high withstand voltage nor decreasing power conversion efficiency.
