“…It was noticed that for quasi-continuous (fast-switching) power regulation, the phase-controlled power regulator could be utilized efficiently with optimization for power performance. A domestic microwave oven of 700 Watt was modified in [6], utilizing a TRIAC to control the magnetron input power. The resultant of microwave power output from the magnetron was measured to evaluate the initial system.…”

“…Where the microwave dries the materials from inside, but the temperature sensor measures the outside surface. The problem of domestic microwave oven [6], is not having a measurement for the state of the loaded material. These problems can be solved by providing a technique for automatic measurement and control on the electromagnetic radiation inside a microwave oven.…”

The Microwave oven is a system used to convert the electromagnetic energy to thermal energy when the microwave cavity is loaded with a dielectric material. The ordinary microwave ovens are not supported with complex features for detecting parameters such as temperature, weight, and loaded material availability. Due to the lack of material availability, several laboratory and industrial applications require these features to switch off the oven. The reflections of electromagnetic radiation inside an empty microwave oven lead to oven damage. An overview of the microwave oven characteristics and emergence of electromagnetic radiation inside a microwave oven is presented in this study. The parameters measured inside the microwave oven, methods for power attenuation in a microwave oven, microwave power detector, and microwave oven leakage are discussed as well. Moreover in the methodology of this work, proposed a new technique based on the measurement of leaked microwave power to control the microwave oven. The preliminary results showed that the leakage measurement of electromagnetic power changes with the state/phase of the material inside the microwave oven, which ensured the possibility of the proposed promising technique. This work will be continued to connect the microwave oven with a spectrum analyzer and computer via hardware and software interfaces depending on the methodology of this article. A computer code will be developed to read the measured power and automatically switch off the microwave oven depending on materials state. Index Terms— Microwave, power, measurement, control.
