    • Occurrence of a defect of the moding phenomenon, etc., accompanying rise in output of a magnetron after power down control is prevented and the reliability of a high-voltage dielectric heating apparatus is further improved. After power down control, when the temperature of a thermistor T1 falls again, the resistance value of the thermistor T1 increases and potential Vpc at a point PC also rises and when the potential Vpc becomes higher than Vc3 of another input potential of a comparator C3 (Vpc>Vc3), the comparator C3 outputs “0.” In association with this, a switch S2 is turned off and PD (power down) 2 of a resistor R7 is turned off and thus the input voltage to a positive terminal A and a negative terminal B of a comparator C1 is again restored to 3 V. When the temperature of the thermistor T1 further falls, the resistance value of the thermistor T1 increases and the potential Vpc at the point PC also starts to rise. When the potential Vpc becomes higher than Vc2 of another input potential of a comparator C2, the comparator C2 outputs “0.” Then, a switch S5 turned on in the power down control is turned off through a switch S4 and an OR gate circuit and the partial pressure action of a resistor R11 does not work. The potential at a point SS starts to rise with charge storage in an electrolytic capacitor CO1. When the potential at the point SS continues to rise and exceeds 3 V, a comparator C4 outputs “1,” a NAND gate circuit outputs “0,” and a moving contact K1 is switched to the side of a second fixed terminal b. The input voltage to the positive terminal A, the negative terminal B of the comparator C1 starts to rise.
    • 伴随着断电控制后的磁控管的输出的上升,发生了模拟现象等的缺陷,并且进一步提高了高压电介质加热装置的可靠性。 断电控制后,当热敏电阻T1的温度再次下降时,热敏电阻T1的电阻值增加,点PC处的电位Vpc也上升,并且当电位Vpc变得高于比较器C3的另一个输入电位的Vc3时 Vcc> Vc3),比较器C3输出“0”。 与此相关联,开关S2断开,电阻器R7的PD(掉电)2断开,因此比较器C1的正端子A和负端子B的输入电压再次恢复到3V 当热敏电阻T1的温度进一步下降时,热敏电阻T1的电阻值增加,点PC处的电位Vpc也开始上升。 当电位Vpc变得高于比较器C2的另一个输入电位的Vc2时,比较器C2输出“0”。 然后,在断电控制中接通的开关S5通过开关S4和或门电路断开,并且电阻器R11的分压作用不起作用。 在电解电容器CO1中电荷存储时,点SS处的电位开始上升。 当点SS处的电位继续上升并超过3V时,比较器C4输出“1”,与非门电路输出“0”,并且移动触点K1切换到第二固定端子b侧。 对于正端子A的输入电压,比较器C1的负端子B开始上升。

    • The invention relates to a high frequency heating apparatus that drives a magnetron such as a microwave, and provides a frequency modulation method of preventing harmonic current occurring due to a high frequency switching operation. When a driving signal is transmitted in order to drive a first semiconductor switching element (3) and a second semiconductor switching element (4), an inverter operating frequency in the every phase of a commercial power supply is provided as a frequency difference (inclination) of the phase range from 0° to 90° using a triangular wave-forming circuit in an oscillation circuit (16). A modulation waveform for a frequency modulation control is formed, configuring an upper limit clamp, a lower limit clamp, a lower limit value corresponding to the lowest frequency in a frequency modulation-forming circuit (15) on the basis of a commercial power rectifying voltage-dividing waveform after rectification. By combining these optimally, it is possible to prevent the harmonic current from occurring while forming the frequency modulation waveform handling several non-uniformities such as constants of major inverter circuit components or a power supply (Vcc) of a driving control IC unit (14).
