WebMOSFETs are widely used in switching power supplies due to their low internal resistance and fast switching speed. The MOSFET often selects a appropriate driver circuit based on the parameters of the power-supply … WebThe switching circuit typically operates from 25kHz up to 500kHz and is a source of EMI. Noise entering from the mains has two components: common mode and differential mode. Common mode relates to noise measured between either live or neutral and earth. Differential noise is between live and neutral.
