BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a time division oscillation circuit of a magnetron, and more particularly, to a time division oscillation circuit of a magnetron that is suitable for a large capacity and a heavy load heating device.

In general, in the case of a dryer, a heater, and a defroster using electrons, a large capacity magnetron may be used or two or more magnetrons may be mounted in order to obtain a high output. It does not take into account the cross-correlation that connects the in-phase waveform of the magnetron to the magnetron anode, resulting in a non-equilibrium distribution due to the tuning of the frequency oscillated in the magnetron, resulting in a high-frequency phenomenon in a particular portion.

Accordingly, an object of the present invention is to input the amplified voltage having a phase developed in the magnetron so that the oscillated frequencies of the magnetron cross each other, and evenly distribute the energy evenly to avoid frequency tuning so as to remove the high field phenomenon at a specific part in the high output device. In order to realize the above object, the present invention provides an input power supply for inputting a voltage, a high voltage transformer for amplifying high voltages of different phases input from the input power supply, and a voltage input from the high voltage transformer. It is composed of a trigger oscillation circuit that triggers each trigger.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a time-division oscillation circuit diagram of a magnetron to be applied to the present invention, and is connected in phase and reverse phase to an input voltage section (a) to which a predetermined voltage is input and a phase of a voltage input from the input voltage section (a), respectively. A capacitor (C1) (C2) oscillating to trigger a magnetron by receiving a voltage output from the high voltage transformer (B) (C) and the high voltage transformer (B) (C) respectively outputting a high voltage corresponding to the phase. And a magnetron trigger oscillation circuit (D) consisting of diodes D1 and D2, respectively.

Referring to the effects of the present invention configured as described above are as follows.

First, as shown in (a) of FIG. 2 from the input voltage unit (a), when an AC voltage is input, a positive (+) period of the input voltage is input to the primary side coil of the high voltage transformer (b). This input voltage is induced in the secondary side coil and outputs the amplified high voltage waveform voltage at both ends of the secondary side coil as shown in FIG. 2 (b). The negative period is input to the primary side coil of the high voltage transformer (c) and is induced in the secondary side coil, and both ends of the secondary side coil output the amplified high voltage waveform as shown in (C) of FIG. .

That is, the high voltage transformer (b) (c) outputs voltages of waveforms 180 degrees out of phase with each other.

As described above, the waveform voltages of the different phases output from the high voltage transformer (b) are input to the capacitors C1, C2 and D1 of the magnetron trigger oscillation circuit d. In this case, the waveform voltage output from the high voltage transformer (b) is 180 ° out of phase with the waveform voltage output from the high voltage transformer (c) to oscillate as a trigger signal for driving a magnetron, and the high voltage transformer (b) Since the waveform voltage outputted from) is later than 180 ° than the waveform voltage outputted from the high voltage transformer (b), the oscillation output is generated as a trigger signal for magnetron driving, and the magnetron trigger oscillation circuit (D) When the output waveform is observed from the time t1 to t10 for a predetermined time, as shown in (d) of FIG. 2, the continuous output waveform voltage is output as shown in (d) of the magnetron. E group existing between the two sides is that by being the cross-crossing operation in that between Crohn's frequency is also behind the half-wave has a rotational frequency as a cross shape in the cross-couple the magnetron avoid tuning kkoehal bone even distribution in energy.

As described above, the present invention comprises a high voltage transformer for outputting a high voltage for each phase of the voltage input to the input power supply unit, and a magnetron trigger oscillator circuit for triggering the voltage output from the high voltage transformer, respectively. By continuously outputting the output waveform voltage with respect to the input waveform voltage, in the magnetron, the electron groups existing between the anode and the cathode inside can cross each other to distribute the energy evenly, thus obtaining high output and large capacity. It will provide an effect.
