The Principles of Switching Power Conversion

This is the entry point into the field of switching power conversion. It starts from the very basics: the charging and discharging of a capacitor and attempts to develop a parallel intuition for the way an inductor behaves when it is carrying current. Replete with real-world analogies, it shows the importance of providing a freewheeling path for the inductor current. That angle of approach eventually leads to the evolution of switching topologies. It also becomes very clear why there are only three fundamental topologies. The voltseconds law in steady state is explained and how that leads to the underlying DC transfer function. Basic converter operation including continuous and discontinuous ...
