Abstract
PURPOSE: To secure the constant wave output of the magnetron to the voltage fluctuation of the commercial frequency power supply by giving the intermittent control to the primary winding current of the boosting transformer.
CONSTITUTION: Switching transistor TR7 is connected in series to primary winding 31 of boosting transformer 3, and the current flowing to winding 31 is intermitted by TR7. Thus, the high frequency of the high voltage is obtained at secondary winding 32 of transformer 3, and then the high frequency is rectified (12) to be supplied to magnetron 13. In this case, the current value of winding 31 is detected via current transformer 10, and control circuit 6 controls on/off of TR7 in accordance with the increase/decrease change of the detected current value in order to give the increase/decrease change to the duty cycle for the base current waveform of TR7. As a result, the current of winding 32 becomes constant to the voltage change of the commercial power supply between terminal a and a', and accordingly the wave output can be kept constant for magnetron 13.
