Rectifiers are used on microwave ovens to do what?

Rectifiers are essential components in microwave ovens because they convert alternating current (AC) from the power source into direct current (DC) required for the microwave's high-voltage components. This conversion is critical because the magnetron, which generates microwave energy for cooking, operates on high DC voltage.

Using rectifiers allows the microwave oven to harness the standard household AC voltage, convert it to a higher DC voltage, and ensure that the magnetron can produce the microwave radiation necessary for cooking food effectively. This process enables the device to function as intended and highlights the importance of rectifiers in the overall electrical design of microwave ovens.
