Short Content: Abstract: , The low power switching power supply's monolithic integration is one of switching power supply's trends of development. Electric circuit's high integration is helpful in develops the high efficiency, the high density, the redundant reliability, the volume small, the weight light high quality power source. But, electromagnetic interference question complexity and latent hazardous nature actually along with it aggravating. Therefore, the electromagnetic interference question's deep research to enhances designs the product the reliability to have the big practical significance. ...
