Introduction

In today’s electronic world, every device—from smartphones to industrial machines—requires a reliable power source. At the core of this is Power Supply Design (SMPS), a technology that ensures efficient conversion of electrical power. By delivering stable voltage with minimal losses, Power Supply Design (SMPS) has become the backbone of modern electronics.

What is Power Supply Design (SMPS)?

Power Supply Design (SMPS) refers to the creation of switch-mode power supplies that convert electrical energy efficiently. Unlike traditional linear power supplies, SMPS uses high-frequency switching transistors and transformers to step up, step down, or invert voltage levels. The result is compact, lightweight, and highly efficient power systems.
