KiCad files and circuit simulation for an inverter circuit. ⚡ Inverter Circuit Simulation 📌 Project Overview
This project demonstrates the design and simulation of an inverter circuit using KiCad. An inverter is an electronic circuit that converts a DC supply into an AC output.
The circuit uses switching components to periodically change the direction of current through the load, thereby producing an alternating output waveform.
🎯 Objective
The main objective of this project is:
To understand the working principle of an inverter. To design the inverter circuit using KiCad. To simulate the circuit and observe the input and output waveforms. To study the conversion of DC power into AC power. ⚙️ Working Principle
The inverter receives a DC input voltage from a power source.
The switching circuit operates alternately, causing the output voltage to change polarity periodically. This creates an alternating waveform at the output.
In simple terms:
DC Input ↓ Switching Circuit ↓ Alternating Switching Action ↓ AC Output 🖼️ Circuit Design
The circuit schematic was designed using KiCad.
The schematic shows the different electronic components and their connections required for converting the DC input into an alternating output.

20 parts, built around the IR2153PBF and IRLZ44N. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the premnathsrinivasan23-ece/Kicad-projects repository on GitHub, at the commit this page was made from: the board is Inverter/Inverter.kicad_pcb and its schematic Inverter/Inverter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask premnathsrinivasan23-ece before reusing the design.
