PROBLEM TO BE SOLVED: To reduce the stress of a switching element by reducing the current change rate of the switching element, to reduce ON loss by reducing the effective value of a current, and, furthermore, to maintain the input voltage waveform of a piezoelectric transformer in nearly a sinusoidal waveform, even when ambient temperature widely changes in a pull/push-type inverter device using the piezoelectric transformer. SOLUTION: In an inverter device provided with a DC power supply E, a pair of switching elements Q1 and Q2 that are alternately turned on and allow a current to alternately flow from the DC power supply E to an inductance element, a piezoelectric transformer 1 where electromotive force being generated at the inductance element is inputted by the switching operation, and a load 2 connected to the output of the piezoelectric transformer, capacitors CS1 and CS2 are connected between the terminal of a side that is not connected to the DC power supply E of the inductance element and at least one end of the DC power supply E. |
