AI Technical Summary
In microwave systems, when the magnetron is in no-load state, it will cause severe heat due to reflected microwaves, which may cause cracks, air leakage, and filament aging, and even damage the equipment.
A magnetron state detection circuit is designed, including a transformer, a voltage double circuit, a sampling circuit and a comparison unit. The anode voltage signal of the magnetron is obtained through the sampling circuit, and the comparison unit is used to compare the anode voltage signal with the reference value to determine the state of the magnetron.
This circuit can quickly and reliably identify the working state of the magnetron, prevent overheating under no load, effectively protect the magnetron, and extend the service life of the equipment.
