Abstract: The electromagnetic noise mechanism and vibration noise control of microwave oven with magnetic leakage transformer are studied. By analyzing the mechanism and transmission path of microwave noise, the noise reduction methods with targeted and efficient are designed to control the vibration and noise of microwave oven. The transmission path of electromagnetic noise caused by transformer is described and evaluated the contribution of each path noise to the whole machine in detail. And, the reasonable analysis method and noise reduction means are applied to reduce the vibration and noise level of the microwave oven.
