Laptop Charger Project

LAPTOP CHARGER DESIGN PROJECT BY ECE 411 I- Introduction The goal of this devise is to innovation an AC-DC converter to power a personal Laptop computer. Chargers ar a approachly component of laptop computer computer. This project ordain implement a design that will lower the cost of the charger. II- Application and Economic Issues The designed AC-DC converter would many functions and benefits. 1. Functions qualify cxx V AC potentiality to 18.5 V DC voltage Supply load 65 Watt Protect against surges Protect against voltage spike 2. Benefits Low cost Safety of laptop III- Application Design Requirement The design of the laptop charger would require the use simulation software. In this project we will bee using PSIM software. IV- Theory of the Design The laptop charger would be designed using a single phase transformer and a rectifier circuit with filter. 1. Transformer We will use a step master transformer with the specification listed in the table below. The transformer is designed to connect in series for AC-DC converter design. It is needed to input at 120 Vdc, and output at 25 Vdc. It is about a 4:1 step down.
