Is this also how switching transformers work?

Not really, except at a high level as capacitors and inductors both store energy. Capacitors store charge as a steady voltage while inductors store magnetic field as a steady current, which results in a different circuit topology.

If you want to learn how switching regulators work, start by studying the basic "boost converter".
