摘要： An RF energy radiation device of this disclosure comprises: an oscillator; a power amplifier; a radiation element; a detector; and a controller. The oscillator generates an RF signal. The power amplifier amplifies the RF signal to output RF power. The radiation element radiates the RF power. The detector detects progressive wave power. The controller performs an RF power output control using a closed-loop control for setting an output set value of the RF power by a closed-loop and an open-loop control for setting the output set value of the RF power by an open-loop. In a burst operation alternately switching between a period of outputting the RF power and a period of stopping the RF power, the controller changes the RF power output control from the closed-loop control to the open-loop control when a specified condition for change is satisfied during the period of stopping the RF power.

摘要： A microwave treatment device comprises a heating chamber for accommodating a heating target, a microwave generator, a feeder, a detector, and a controller. The microwave generator generates a microwave having a frequency in a specified frequency band. The feeder radiates the microwave inside the heating chamber. The detector detects a reflected microwave power reflected from the heating chamber. The controller causes the microwave generator to execute a frequency sweeping in the specified frequency band. The controller also controls the microwave generator according to a temporal change in a frequency characteristic of the reflected microwave power. The temporal change in the frequency characteristic of the reflected microwave power is based on the frequency of the microwave, a level of the reflected microwave power, and a time passed from a start of heating. In this aspect, it is possible to accurately recognizes the progress of cooking while heating the object. Accordingly, cooking can be finished appropriately.
