Abstract :
An equivalent disturbance generator model that considers the snubber circuit is applied to predict the emission of a flyback-type switched-mode power supply. Common and differential mode voltages are calculated using a SPICE simulator. The conducted emission and its common mode component are measured to validate the prediction model
