The Standby Power Reduction SMPS is a Power Electronics project that combines Protection circuits and High frequency stage, built with LTSpice. The project follows a clean, modular pipeline where power conversion, control, and monitoring stay separated, making it easy to test, extend, and present. It showcases practical Power Electronics techniques while producing a working, demo-ready system.
Conventional power systems for this task are inefficient, costly, and lack precise control. Without a Power Electronics approach built on High frequency stage and LTSpice, users cannot efficiently convert, regulate, and control electrical power, and there is no reliable way to monitor or improve performance.
This project applies Power Electronics techniques through Protection circuits, orchestrated with LTSpice and High frequency stage. The system is designed for efficiency and safety, with power stage design, control logic, and clear evaluation. It produces consistent, reusable results and can be adapted to related power tasks with minimal changes.
