Difference between frequency conversion microwave oven and traditional microwave oven

Frequency conversion microwave oven adopts the most advanced frequency conversion technology in the world at present, which converts the power frequency of 50 Hz in household power supply system into high frequency output of 10000 ~ 30000Hz at will. The traditional microwave oven outputs constant power at a fixed frequency of 50 Hz. If different power needs to be output, it can only be simulated by the length of on/off time interval, which will lead to the uneven phenomenon that part of the heated food is repeatedly heated and the other part is insufficiently heated.
