摘要： An operating state detection technique is provided which makes it possible to accurately detect an abnormality of a high-frequency heating apparatus. An anode current detected by the anode current detection resistor 40 of a magnetron is inputted into the A/D converter terminal of a microcomputer 27 on a control panel circuit board side. The current is subjected to an analog-to-digital conversion to thereby obtain an anode voltage IaDC value. The microcomputer 27 determines an operating state based on a plurality of the anode voltage IaDC values thus read. Further, the microcomputer 27 obtains a summed value of the IaDC values corresponding to one period of the revolution of rotary antennas 68, 69 to thereby determines the operating state of the high-frequency heating apparatus 100 based on the summed value. According to the aforesaid IaDC value reading method, it makes it possible to accurately detect an abnormality without an erroneous operation also in correspondence to the change of the feeding distribution. Further, the microcomputer 27 changes, in accordance with the set output of the high-frequency heating apparatus, a threshold value used for determining the abnormality and a changing value (increasing amount) from the start of the operation with respect to the change of the output of the apparatus and the operating state of a heated subject etc., whereby it makes it possible to accurately detect an abnormality without an erroneous operation.

摘要： It is an object of the present invention to provide a power supply for a high frequency heating that suppresses an over-shoot of an input current generated under an unstable state immediately after a magnetron begins oscillating.When processes from a non-oscillation to an oscillation of a magnetron (12) are finely classified, the non-oscillation (a start mode), the oscillation (a start mode) and the oscillation (a steady mode) are obtained. A problem resides in an unstable state immediately after the oscillation. When a PWM setting value at this time is set to a value lower than a PWM setting value in the steady mode, even if the PWM setting value during the steady mode is set to a maximum output value, the input current is not controlled to a large current including the over-shoot immediately after the oscillation. After the magnetron shifts to a stable state, the PWM setting value shifts to a PWM setting value of an actual steady mode, so that the over-shoot of the input current can be suppressed as much as possible.
摘要翻译：本发明的目的是提供一种用于高频加热的电源，其在磁控管开始振荡后立即抑制在不稳定状态下产生的输入电流的过冲。当从磁控管（12）的非振荡到振荡的过程被精细地分类时，获得非振荡（起动模式），振荡（起动模式）和振荡（稳定模式）。振荡后立即出现不稳定状态的问题。当此时的PWM设定值被设定为比稳定模式下的PWM设定值低的值时，即使稳定模式下的PWM设定值被设定为最大输出值，也不将输入电流控制为包括震荡后立即过拍的大电流。在磁控管移动到稳定状态之后，PWM设定值转移到实际稳定模式的PWM设定值，能够尽可能地抑制输入电流的过拍。

摘要： The object of the invention is not only to simplify the structure of a high frequency dielectric heating power control apparatus and reduce the size of the apparatus but also to eliminate the need for control and design corresponding to the kind of a magnetron and thus enhance the running efficiency of the apparatus.An input current to an inverter circuit is detected by a shunt resistor 71 and is converted to an input current wave form through an input current signal amplifier 72. On the other hand, based on an alternating current power supply voltage wave form from an alternating power supply voltage, there is obtained through a gain variable amplifier 91 a reference wave form following the size of the input current wave form. A wave form error detect circuit 92 compares the input current wave form with the reference wave form to obtain a wave form error signal. A comparison circuit 74 compares the input current wave form with an input current reference signal obtained from an output setting part 75 for obtaining a desired high frequency output to thereby obtain a current error signal. And, a mix and filter circuit 81 adds the wave form error signal and the current error signal to obtain a power control signal for driving a switching transistor 39 of the inverter circuit. Here, the reference wave form is generated based only on the alternating current power supply voltage wave form and on the feedback signal of the wave form error signal.
