This very stern looking gentleman is about to explain how voltage doubles work in a plodding, yet satisfyingly thorough manner. We’re not certain when this US Air Training Command video was produced.

While most readers are knowledgeable about voltage doublers, here is a discussion about how to use them in unusual ways to enhance power supply circuits that might be otherwise limited in features.

For high voltage input/output applications, inductor-less, switched capacitor converters (charge pumps) significantly improve efficiency and reduce solution size over conventional inductor-based buck ...
