 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 the design is to enhance transformer efficiency and reduce harmonic current. To validate the proposed design, a 250W prototype circuit was constructed , 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.
