In this video we will be having a closer look at the SEPIC voltage converter. You probably do not know it, but most small Buck Boost Converters are in fact SEPIC converters and for a good reason. I will show you how the SEPIC converter works, why it is "(S)EPIC", how you can modify it with a coupled inductor and how to make a DIY version. Let's get started!
