摘要： PROBLEM TO BE SOLVED: To solve the problem of the increase of harmonics of power source wave-form caused by the temperature characteristics of a magnetron, for a high-frequency heating device. SOLUTION: The high-frequency heating device comprises an inverter 24 equipped with a modulation part 21, a driving part 22, and a semiconductor switching element 23 and a magnetron 25 driven by the inverter 24. The modulation part 21 generates a modulation signal depending on a power source voltage detecting means 27 detecting the voltage of power source 26 supplied to the inverter 24, and a magnetron operating voltage detecting means 28 detecting the operating voltage of the magnetron 25. The driving part 22 determines the pulse signal to drive the semiconductor switching element 23 depending on the above modulation signal. Accordingly, even if the operating voltage is changed by the temperature characteristics of the magnetron 25, an optimum modulation signal can be obtained and the harmonics of input current are reduced.
