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 […]

100 Watt Power Amplifier Circuit Diagram using a Single IC TDA7294

Last Updated on January 17, 2025 by Swagatam 4 Comments

100 watt power amplifier circuit using TDA7294 IC

Building a power hi-fi amplifier with MOS transistors requires the implementation of a relatively large number of components because, at the level of power stages, the connection between the bipolar transistors that make up the input stages and the MOS transistors of the output stages is far from simple. Fortunately, there is an elegant solution […]

75 Watt Power Amplifier Circuit

Last Updated on August 24, 2023 by Swagatam 2 Comments

75 watt amplifier circuit

Our power amplifier only uses a handful of widely available and inexpensive components. Despite this, it can deliver an effective power output of 50 W into an 8 ohm load or 75 W into a 4 ohm load. If distortion is below 0.3% at these maximum power levels, it drops to less than 0.01% from […]

22 Watt Stereo Amplifier Circuit using TDA1554

Last Updated on January 5, 2023 by Swagatam 2 Comments

PCB layout TDA1554

The IC TDA1554 based Amplifier circuit discussed in this article can provide up to 22 watts per channel into a couple of four-ohm loudspeakers. The main attraction is that you can construct it for less than $15. This implies that you may make a power amplifier for your car’s front speakers, another for the back […]
