Claims

[Scope of utility model registration request]

A pair of semiconductor switches are connected to a bush pull to the primary winding of an oscillation transformer divided by a center tap, and a DC power source is connected between the center tap and a common connection part of the pair of semiconductor switches, This DC power supply was connected, an inductor was inserted and connected to the input line from this DC power supply, and a capacitor was connected to either the primary winding or the secondary winding of the oscillation transformer to form a parallel resonant circuit. In the inverter, a pair of diodes connected in series with each other so as to have the same polarity as each of the pair of semiconductor switches is connected in parallel with the series circuit of the pair of semiconductor switches, and the connection point of the pair of semiconductor switches and the pair of diodes are connected in parallel with the series circuit of the pair of semiconductor switches. An inverter characterized in that a surge absorption circuit consisting of a series circuit of a capacitor and a resistor with a discharge resistor connected in parallel is connected between the connection point of the diode and the resistor.
