How to Build a Simple Inverter Circuit Using MOSFETs: A Step-by-Step Guide

Inverters are essential devices that convert DC (Direct Current) power into AC (Alternating Current) . Whether you're powering appliances from a solar battery or building a backup system, a MOSFET-based inverter is a great place to start for hobbyists, students, and engineers alike. In this article, I’ll guide you step by step on how to build a simple square wave inverter using MOSFETs , explain its working principle, and answer some frequently asked questions. 🔧 What You'll Learn: Basics of how an inverter works Components required Circuit diagram and working principle Step-by-step construction process Example calculations for sizing Safety tips and testing Frequently asked questions ⚙️ 1. Understanding the Basics ❓ What is an Inverter? An inverter converts DC power (e.g., from a battery or solar panel) into AC power that can be used by household appliances. The most basic inverters generate square waves , while advanced models produce sine or modified sine waves . ⚡ Why Use MOSFETs? MOSFETs …
