Abstract
A method for controlling the microwave feed in a microwave oven, as well as a microwave oven for implementing the method, is disclosed. The power level (P) of the microwaves is controlled by periodic activation or inactivation of the microwave radiation source of the oven during a sequence of control cycles. The oven has a rotary bottom plate carrying the food or dish, and/or a rotary field agitator or aerial. The heating uniformity is improved by adjusting to one another the duration of the control cycle and the revolution time of the bottom plate or of the field agitator or aerial, while taking into consideration the aimed-at power level. In a procedure composed of several steps with different power levels and heating times, the heating times of the different steps are also adjusted to the current control-cycle duration.
