20.500.12556/RUL-184822 Active snubber solution for an interleaved flyback converter This paper presents an energy-recovering active snubber in which the energy captured by the snubber capacitor is transferred back to the converter’s input using an auxiliary inverting switching stage. The snubber operates independently of the main power stage and can therefore be applied to a wide range of isolated converter topologies without modifying their primary control or structure. The proposed snubber achieves an energyrecovery efficiency of approximately 80%, thereby reducing snubber-related losses by the same proportion. As a representative implementation, the concept was experimentally validated in a 550 W dual-phase interleaved DC–DC flyback converter, where it improves the overall converter efficiency by 1.6 percentage points and reduces total losses by 18% compared with a dissipative snubber solution. The proposed snubber supports a wide input-voltage range and is well suited for multiphase converters, as most of its components can be shared between phases. active snubber flyback converter leakage inductance regenerative snubber aktivno razbremenilno vezje zaporni pretvornik stresana induktivnost regenerativno razbremenilno vezje true false true Angleški jezik Slovenski jezik Članek v reviji 2026-07-15 13:39:14 2026-07-15 13:39:14 2026-07-17 03:50:47 0000-00-00 00:00:00 2026 0 0 12 str. iss. 13, art. 2937 Vol. 15 Jul-1 2026 0000-00-00 Zaloznikova Objavljeno apc 0000-00-00 0000-00-00 0000-00-00 621.314.2 2079-9292 10.3390/electronics15132937 284923139 electronics-15-02937-v2.pdf electronics-15-02937-v2.pdf 1 910F097C9EEC8EE484129FC44CB90F62 6fa2f270b9f12d9d91844824325b2fff52ba0757cfba0fcefdc40113e5891788 bbe3dbc6-8041-11f1-9b0d-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=240118 https://www.mdpi.com/2079-9292/15/13/2937 1 a0cbeb7b-8041-11f1-9b0d-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=240117 Fakulteta za elektrotehniko 0 0 0
