SEPIC DC/DC Converter with Coupled and Uncoupled Inductors
The Single-Ended-Primary-Inductor-Converter, popularly known as SEPIC, is a non-isolated, switching power supply topology generating an output voltage that can be higher or lower than the input voltage. This is a common requirement in battery-powered applications as well as those with fluctuating input and/or output voltages, like photovoltaic converters (PV), automotive electronics, offline LED lighting and battery chargers, amongst others.
Using a coupled inductor instead of two uncoupled inductors can bring some advantages, like requiring less inductance for the same ripple current amplitude, or lower EMI input filter requirements when a technique known as ‘ripple current steering’ is implemented, both leading to potential cost savings.
