The Future Of Microwave Cooking

The future of microwave cooking is solid-state power amplifier (SSPA)

The good old magnetron does a high quality job delivering microwave energy in the microwave ovens.  However the magnetron has limitations. It solely has on-off control and the mixture of the magnetron and cooking cavity makes hot-spots and cold-spots within the meals. Use of turntable and the stirrer helps preventing hot spots and cooks meals equally. With the use of solid-state power amplifier we will get faster and more delicate cooking.

Manufacturers of solid-state power amplifiers see it as a powerful potential progress market simply because these units can substitute the magnetron’s function in the microwave ovens. So, will the SSPA-based microwave quickly replace the magnetron-based one in your house? The higher cost of the SSPA (for now) is definitely an issue. It’s seemingly that the biggest SSPA usage will come in commercial settings with their greater efficiency, lower operating cost, and longer life.

Maybe the hi-end microwave ovens will have a label on the front panel declaring “Solid State Power Amplifier Inside".

    How To Troubleshoot Magnetron

    How To Troubleshoot Magnetron

    Magnetron is designed to generate microwaves. The physics of the magnetron is quite complicated. It is using strong external magnetic field to direct the flow of electrons in a resonant circular cavity developing tens and hundreds of watts at frequencies around 2.45 GHz. Magnetron can be tested on continuity only. The volume resistance of the terminals should be less than 1Ω. The insulation resistance between the two terminals and the housing should be infinite.

    It may also be possible to detect faulty magnetron when it starts making loud humming noises. A magnetron with a short between the filament (cathode and anode) is likely to cause a loud hum when the cook cycle is initiated. Evidence of arcing (burned spots around ventilation holes in base or a burnt odor) usually indicates a bad magnetron as well. Melting or other damage to the antenna might be the result of arcing due to problems in the oven cavity or waveguide, perhaps operating microwave oven with nothing inside the oven.
