<p>A microwave oven 2 having a cabinet 4, a door 6, a programming interface 15, a magnetron tube that capable of being dynamically controlled, a controller configured to control the magnetron tube 166, and a microwave generating system is described. A method of dynamically controlling the magnetron tube 166 in the microwave oven by utilizing a magnetron power supply is also described. By monitoring a current to the magnetron power supply, determining the current to the magnetron power supply at which the magnetron tube 166 conducts, calculating a time base, and adjusting the time base as the power level required is increased, the control produces consistent power when the magnetron tube 166 is cycled at less than a 100% power level and to compensate for a slow start of the magnetron tube 166 during a short cook cycle.</p> |
