Abstract
An apparatus and method for controlling cooking in a microwave oven whereby the power input to the cooking cavity is held at a predetermined, constant level. Available line power is measured through a winding or tap on the high voltage transformer secondary and the duty cycle of the magnetron power supply is adjusted to maintain a constant average power output.
