In this post I have explained how to trick an inverter’s “no load auto-shutdown” feature through an external circuit so that the inverter may be kept running even with minor, below permissible loads at the output. The idea was requested by Mr. Em. Technical Specifications Thanks for your prompt responses and guidance. I was wondering […]

SMPS Welding Inverter Circuit
If you are looking for an option to replace conventional welding transformer, the welding inverter is the best choice. Welding inverter is handy and runs on DC current. The current control is maintained through potentiometer. By: Dhrubajyoti Biswas Using Two Switch Topology When developing a welding inverter, I applied forward inverter with two switches topology. […]
Simple H-Bridge Inverter Circuit using IR2184 ICs
In this post we will try to understand this full bridge or H-bridge inverter circuit using IR2184 ICs. Let us begin breaking it down section by section. If you do not want to read the full article, you can simply watch the following video instead: What This Circuit is Doing: So here basically we are […]
Simplest Full Bridge Inverter Circuit
Among the different existing inverter topologies, the full bridge or the H-bridge inverter topology is considered to be the most efficient and effective. Configuring a full bridge topology could involve too many criticality, however with the advent of full bridge driver ICs these have now become one of the simplest inverters one can build. What’s […]
250 Watt Pure Sine Wave Inverter Circuit
The cost and quantity of parts necessary to develop the proposed 250 watt sine wave power inverter circuit is actually much less compared to a noisy square wave switching-type inverter circuit. Only an extra three or four tiny transistors, a some resistors and capacitors, a couple of pots and a small driver transformer are all […]
2 Easy Automatic Inverter/Mains AC Changeover Circuits
I have been put forth with this question many times in this blog, how do we add a changeover selector switch for automatically toggling of an inverter when AC mains is present and vice versa. And also the system must enable automatic switching of the battery charger such that when AC mains is present the […]
