A typical SEPIC converter schematic is shown on this slide. The name “SEPIC” is an abbreviation of the circuit description: Single Ended Primary Inductor Converter. The SEPIC topology is non-isolated, meaning that the input and output share a common return or ground connection. The main feature of this circuit is that a regulated output voltage is delivered over a wide range of input voltages that vary from higher than to lower than or equal to the output voltage. One benefit of SEPIC converters is that the input ripple current is continuous if large enough inductor values are selected. Operating in the continuous conduction mode reduces EMI and prevents interference with other circuits operating from the same power source.
