Transformers for microwave ovens
High-voltage transformers for microwave ovens are special magnetic flux leakage transformers. There are three windings in the high-voltage transformer. One of the primary windings, AC 220V mains voltage is applied in this winding; two are independent secondary windings.
When the magnetron is operating, the oscillating current flows in the secondary high-voltage winding of the transformer, causing magnetic saturation in the core near it. Assuming that the magnetron anode voltage rises and the anode current increases due to mains fluctuations, etc.,
