How Is A Microwave Oven Made?
You pop open the door to the microwave oven, slide in your frozen dinner, push a few buttons and sit back down in front of the TV. When the buzzer goes off you head back to the kitchen, grab your quickly cooked food and head back to the easy chair. How convenient. That part is easy, but did you ever wonder how a microwave is made? There are several parts that make up a microwave oven. One of them is the high voltage transformer. This takes the electricity that comes into the microwave and hands it off to the next part, the magnetron. The magnetron then converts the high voltage electricity turning it into microwave radiation (this cooks the food). There is also a magnetron control circuit with a microcontroller and a wave guide (more about those in a minute) and of course the place where you put the food, the cooking chamber. Microwave ovens actually use frequencies similar to a radio to cook the foods. There are some restrictions that are placed on those frequencies, also called ISM b
