Abstract: Powering the modern world requires increasingly efficient energy conversion systems. This paper presents the design and step-by-step implementation of a high-efficiency DC-DC power converter for DC drive motor applications. A flyback converter circuit uses MOSFETs, capacitors, transformers, and microcontrollers to provide well- regulated DC output voltage through calculations, simulations, and testing. Key stages explained include the AC-DC conversion and rectification, flyback transformer with PWM control, and output regulation. Extensive MATLAB and Proteus software simulations evaluate anticipated performance before constructing the hardware converter. Testing with oscilloscopes compares real-world results against design goals for voltage regulation and efficiency. The paper demonstrates that careful engineering design and testing enable building a functional, high-efficiency DC-DC converter with 95-100% measured efficiencies. Overall, this work details the process of creating an efficient power electronics system for motor drive applications, from calculations to software simulations to hardware implementation.
