Abstract

The paper presents a design of a single-stage single switch flyback transformer, which incorporates two auxiliary windings and a curved air gap. The main objective of this design is to enhance transformer efficiency and reduce harmonic current. To validate the proposed design, a 250W prototype circuit was constructed, simulations and experiments were conducted using four ferrite materials. The results obtained from both FEM simulations and experiments are promising, indicating the effectiveness of the design. The proposed transformer configuration demonstrated improved efficiency and a reduction in harmonic current.
