  • LC Regenerative Snubber for SEPIC Converter

    The SEPIC converter is a type of DC/DC converter commonly used in electric vehicle (EV) applications. Unlike regular buck-boost converters, the output voltage polarity in the SEPIC converter is non-inverting. However, it suffers from energy stored in the leakage inductance of the primary inductor, which can damage the MOSFET switch. A snubber circuit is used to protect the switch, and ringing created from resonance increases the EMI of the converter.
