ABSTRACT:
A magnetron driving control apparatus of a microwave oven and a method thereof by which a magnetron is continuously driven when an output level selectively input by a user belongs to a continuous driving output range, and when the output level exceeds an established time, the magnetron is intermittently driven according to a predetermined period to allow a high voltage transformer to cool by itself during the period the driving of the magnetron is stopped, thereby preventing the high voltage transformer from becoming over-heated and avoiding the high voltage transformer from becoming larger in size to decrease a heat generated by an electric resistance.
