ABSTRACT:
A microwave oven having a pulsed magnetron comprises a timing circuit which determines a cooking time and the pulse duration when the magnetron is pulsed. By means of a time and power setting device, the cooking time and the pulse duration are adapted to a food introduced into the oven chamber. At least one operation parameter affecting the magnetron output is measured and compared with the nominal value of the parameter. In the event of a difference between the measured and the nominal parameter value, the cooking time and/or the pulse duration is/are corrected in relation to the set values in order to eliminate the effect of this difference on the total quantity of energy supplied during cooking.
