Transformer design considerations for noncontinuous mode, boost, flyback converters [PDF]

Proceedings:Electrical Electronics Insulation Conference and Electrical Manufacturing & Coil Winding Conference, 2002
This paper presents some design considerations for small, flyback transformers used to charge energy storage capacitors from 0.1 to 5 kV from a low voltage DC source. The transformer has two roles: to act as an energy storage device, and to ratio the primary to secondary voltages.

A Hybrid Grid and Photovoltaic Dual‐Input Battery Charger

IET Power Electronics, Volume 19, Issue 1, January/December 2026.
This paper proposes a dual‐input battery charger (DIBC) with grid power and solar energy. The proposed DIBC consists of a boost‐type power factor correction (PFC) circuit, a high step‐down DC converter (HSDDC), and a buck switch. The grid charges the battery through the boost‐type PFC circuit combined with the HSDDC, while the solar module charges the ...
