７A DC voltage circuit that rectifies an AC power source and outputs a DC voltage, and a control signal input switching element that is connected to this DC voltage circuit and operates on and off in a predetermined switching cycle in response to a control input from an external control circuit. , an amplifier circuit that uses the output of the DC voltage circuit as a power source and amplifies the on/off output of the control signal input switching element to drive the base of the inverter transistor; and a transistor connected in series with the control signal input switching element. and a Zener diode that is connected to the DC voltage circuit and applies a bias to the transistor, and the Zener diode stops the reverse current in response to a gradual decrease in the output level of the DC voltage circuit at the time of a power outage, thereby stopping the transistor from power outage. A pace driver circuit for a transistor inverter, characterized in that the transistor-inverter pace driver circuit is configured to immediately turn off and disable the control signal input switching element regardless of the control input from the external control circuit.
