Abstract: A high frequency generating device used in a plasma ignition apparatus according to an embodiment includes a high frequency output unit, an output control unit, a current detecting unit, and an abnormality detecting unit. The high frequency output unit outputs a high frequency. The output control unit shifts a state of the high frequency output unit from a non-output state to an output-ready state of the high frequency. The current detecting unit detects a current that flows through a power-supply path to the high frequency output unit. The abnormality detecting unit detects output abnormality of the high frequency in the non-output state when a value of a current detected by the current detecting unit in the non-output state exceeds a non-output threshold.

Abstract: A control device of a plasma ignition apparatus according to an embodiment includes a plug socket, an oscillation unit, and an amplification unit. The plug socket holds an ignition plug, and a high voltage generated by an ignition coil is transmitted to the ignition plug through the plug socket. The oscillation unit oscillates a high frequency. The amplification unit amplifies the high frequency oscillated by the oscillation unit. The oscillation unit is arranged outside of the plug socket and the amplification unit is arranged inside of the plug socket.
