Introduction

A picture emerges in all time-domain simulations conducted earlier. That is the sharp transitions of either current or voltage in all switches; power transistors or rectifier diodes, in particular in the output side circuits. Such movements of currents at high time-rate generate a lot of conducted or radiated emissions that easily become sources of electromagnetic interference (EMI). A need, therefore, arises to tame the situation. And Chapter 9 presents one of the ways to meet the goal: reducing EMI at the source.
Another picture also emerges in all chapters presented so far. That is the voltage sourcing nature of all converter outputs shown earlier. Without additional measure, voltage source is more susceptible to overload (overcurrent) ...
