Inductors, Power line chokes, Sine-wave chokes
General. In switch-mode power supplies, the line input current is not a sine-wave curve like the line voltage but is pulse-shaped. This current function puts a load on the power supply network and distorts the network''s voltage curves. With the aid of a "pump circuit" built up around a "sine-wave choke", it is possible to modify

The Fundamentals of Inductors in AC Circuits
Inductors store energy as a magnetic field, which is returned to the circuit when the field collapses. This happens every half cycle, and as there is no resistance (in theory), there are no losses, and all of the energy is returned to the circuit. Figure 1 shows the applied voltage as the red sine wave and the back EMF as the green sine wave.
A Guide to Flyback Transformers | Coilcraft
A flyback transformer is a coupled inductor with a gapped core. During each cycle, when the input voltage is applied to the primary winding, energy is stored in the gap of the core. It is then transferred to the secondary winding to provide energy to the load. Flyback transformers are used to provide voltage transformation and circuit isolation
