ベル信号に落とすことを特徴とするインバータ。[Claims for Utility Model Registration] Drive signals generated by a drive signal source and having opposite phases to each other are received by two buffers, and two switching elements are alternately driven by the outputs of these buffers to generate a DC voltage. in an inverter for converting into an alternating current voltage, a differentiating circuit provided for each buffer, comprising a resistor and a capacitor, and connected between the output end of the drive signal source and the input end of the buffer; The buffer has a diode whose anode is connected to the input end of the buffer and whose cathode is connected to a power supply potential point, and an input protection diode whose anode is connected to a common potential point and whose cathode is connected to the input end of the buffer. When the level of is fixed, the output of the differentiating circuit connected to the buffer that outputs the H level signal changes with a time constant given by the resistor and capacitor, and reduces the output of this buffer to the L level signal. Features of the inverter.
