4.- To approximate the large signal model for a lineal one, obtaining, this way, a small signal model for the topology.
The Kettering ignition system is a mechanically-switched version of a fly back boost converter; the transformer is the ignition coil.
Variations of this ignition system were used in all non-diesel internal combustion engines until the 1960s when it began to be replaced first by solid-state electronically-switched versions, then capacitive discharge ignition systems.
Unlike a linear power supply, the pass transistor of a switching-mode supply continually switches between low-dissipation, full-on and full-off states, and spends very little time in the high dissipation transitions, which minimizes wasted energy.
A hypothetical ideal switched-mode power supply dissipates no power.
