An Isolated SEPIC‐Based AC‐AC Converter for Voltage Sag/Swell Mitigation
IET Power Electronics, Volume 18, Issue 1, January/December 2025.ABSTRACT This paper proposes a high‐frequency isolated buck‐boost AC‐AC converter based on the single‐ended‐primary‐inductance‐converter (SEPIC) topology and its extension circuit with bipolar output. The proposed converters can achieve a wide range of voltage step‐down and step‐up operations with both same‐ and reversed‐phase outputs.

Interleaved Boost-Flyback Converter with Boundary Conduction Mode for Power Factor Correction [PDF]
Journal of Power Electronics, 2012 This paper presents a new interleaved pulse-width modulation (PWM) boost-flyback converter to achieve power factor correction (PFC) and regulate DC bus voltage. The adopted boost-flyback converter has a high voltage conversion ratio to overcome the limit of conventional boost or buck-boost converter with narrow turn-off period.
