Chapter 8

We see that the fundamental properties and behavior of an inductor are ultimately

responsible for the significant

V-I overlap during crossover.

The same situation is present in the case of any switching topology. Therefore, the

switching loss equation presented earlier also applies to all topologies. What we have

to remember is, that in our equations, we are referring to the voltage across the switch

(when it is OFF), and the current through it (when it is ON). In an actual converter, we

will need to ultimately relate these V and I to the actual input/output rails and load current

of the application. The procedure ...
