      abstract = {Switched Mode Power Supply (SMPS) units are critical for powering modern electronic systems due to their superior efficiency and compact size. This paper presents the design, construction, and experimental evaluation of aflybackSMPS intended for low-power electronic devices. A flyback converter topology operating in discontinuous conduction mode (DCM) was utilized, targeting a wide AC input range of 85V to 265V and delivering a regulated 12V DC output voltage at 0.67A. The performance assessments revealed that the developed SMPS maintains stable output even at low input voltages (down to 40V), significantly outperforming a conventional linear power supply in regulation and efficiency. The SMPS achieved an average efficiency of 79.3%, making it a cost-effective and reliable alternative to imported models. The system is suitable for use in educational, research, and domestic applications.},
