Abstract: A radio frequency (RF) generator including a carbonization prevention system includes a casing on which an intake fan and an interlock are mounted, an alternating current (AC) power supply, a power supply, a power amplifier (PA), a coupler provided between the PA and the RF output connector, and a control board that controls an amount of DC power output to the PA according to the calculated values. The carbonization prevention system detects smoke generated in the casing, measures a temperature and a humidity in the casing, and generates and transmits a control signal to the control board and an operation control signal to the interlock according to a reading result.
