Part 2 of this series covers specialized topologies, common isolated topologies, and advanced isolated topologies of power supplies.

What you’ll learn in this article:

  • What other topologies are used for SMPS beyond the three most common types?
  • Common and advanced isolated topologies.
  • What is the switched capacitor converter?

Beyond the three basic, nonisolated switch-mode power-supply topologies discussed in Part 1 of this series, many more topologies are available. However, they all require additional power components, which typically makes them higher cost and lowers their power-conversion efficiency. With certain exceptions, adding additional components in the power path will generally add losses…
