。 A transformer that connects a first switching element and an inductive load in series to a DC input voltage source, turns on and off a second switching element connected to a primary winding, and outputs a control voltage from the secondary winding. , a drive circuit having two drive FETs that are push-pull connected to the secondary side of the transformer and supply a drive signal to the first switching element based on the control voltage; In the inverter that controls on/off of a switching element to flow an alternating current to the load, the drive circuit connects the first inverter between the drive FET that turns off the switching element and the negative input line of the DC input voltage source. A capacitor is inserted and connected to make the drive signal for turning off the switching element into a negative voltage, and in order to discharge this capacitor, the connection point between the drive FET and the capacitor is connected to the control voltage supply line via a backflow prevention diode. A switching element drive circuit for an inverter, characterized in that it is configured by being connected to.
