Explained: Snubber Circuit for MOSFET H-Bridge

Last Updated on June 8, 2025 by Swagatam Leave a Comment

Here we are going to talk deeply about snubber circuits and why we must use them with MOSFET H-bridge circuits. Because if we do not put snubber in H-bridge then that MOSFETs might blow off during switching. Specially when we drive inductive loads like transformer, motor, relay, solenoid, etc. then this thing becomes very serious. […]

100A AC Load Monitoring Circuit using Arduino, Watt Limit, LCD, Alarm, Auto Shutdown

Last Updated on June 3, 2025 by Swagatam 2 Comments

In this project we are going to make one very useful grid power protection circuit. This will be like a power guard system which we can use in homes or apartments to monitor the wattage of the load and also to cut off the load automatically if it starts taking too much wattage, more than […]

Making an EGS002 Equivalent Board using Arduino

Last Updated on May 28, 2025 by Swagatam Leave a Comment

The EGS002 board is nothing but a combination of a microcontroller with a H-bridge driver like the IR2110. So if you are interested to build your own EGS002 equivalent board with exactly identical features, then you can do it using the instructions given in the following article. So, here we are trying to build our […]

BQ24295 Smart Battery Charger IC with Boost + OTG

Last Updated on May 29, 2025 by Swagatam Leave a Comment

This BQ24295 IC is like a super smart charger chip. This one is not just for charging battery, but also doing many other jobs like boost converter, USB detection, power path control, and even OTG (host power supply). So we can say that this is a full battery charging and power management IC. Let us […]
