A grid tie inverter works quite like a conventional inverter, however the power output from such inverter is fed and tied with the AC mains from the utility grid supply. As long as the mains AC supply is present, the inverter contributes its power to the existing grid mains supply, and stops the process when […]

How to Design an Inverter – Theory and Tutorial
In this post I have explained the fundamental tips and theories which may be useful for the newcomers while designing or dealing with basic inverter concepts. I have explained more. What’s an Inverter It’s a device which converts or inverts a low voltage, high DC potential into a low current high alternating voltage such as […]
300 Watts PWM Controlled Pure Sine Wave Inverter Circuit
The following article which discusses a 300 watt pure sine wave inverter circuit with automatic output voltage correction, is a modified version of one of my previous posts, and was submitted to me by Mr. Marcelin. I have explained more about the converter implementations. The Design The idea was inspired by the design presented in this article […]
Sine Wave Inverter using Bubba Oscillator Circuit
In this post I have explained how to make a simple sine wave inverter using bubba oscillator sine wave generator. The idea ws requested by Mr. Ritwik Naudiyal. Technical Specifications I am a 4th year B.Tech Student Electrical Eng. We are trying to make pure wave sine wave inverter using PWM and bubba oscillator for […]
What’s Islanding in GTI (Grid Tie Inverter)
One big issue that most GTI manufacturers struggle to implement effectively is, what is commonly known as “islanding”, the following discussion throws light on this important factor and tries to find a solution. The issue was pointed out and clarified by Mr. Dennis, I have explained more. What’s GTI Islanding G’day, With any luck at […]
No Load Detector and Cut-off Circuit for Inverters
In this post I have explained a relay cut-off circuit which may be included in inverters to ensures that under a no load at the output the condition is quickly detected and the supply cut off, preventing the inverter from operating unnecessarily. The idea was requested by Mr. Rajath. Technical Specifications I need to adopt […]
