IR2111 H-Bridge Inverter Circuit with Soft Start
Here we see this circuit diagram which is full H-Bridge using 4 power MOSFETs and 2 IR2111 high side driver ICs. That means this circuit is for making full bridge inverter which converts DC into AC. Power Supply Part We have +600V DC at top rail, written as +600V max. And ground (0V) at bottom. […]
Solving Inverter “No Load Auto-Shutdown” Problem
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. […]
