120 Watt Amplifier Circuit using TDA 2030 IC
An impressive 120 watt amplifier circuit can be built by cascading a couple of TDA 2030 IC in a bridged tied load (BTL) configuration and through a few current boosting transistors. Advantage of a BTL Amplifier Topology The main objective of a BTL configuration is to enable a two way operation of the load which […]
30 Watt Amplifier Circuit using Transistors
The three watt amplifier circuit discussed in the earlier post could be effectively upgraded into a 30 to 40 watt transistorized amplifier circuit, simply by adding a 2N3055 power output stage. The entire procedure for this is explained in the following article. The circuit was requested by Mr. Clifford. The requested specifications can be viewed […]
100A AC Load Monitoring Circuit using Arduino, Watt Limit, LCD, Alarm, Auto Shutdown
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 […]
SMPS 50 watt LED Street Light Driver Circuit
The post presents an SMPS based LED street lamp driver circuit which can be used for driving any LED lamp design right from 10 watts to 50 watts plus. Using the IC L6565 The proposed 50 watt (and higher) LED street light driver circuit uses the IC L6565 as the main control device, which is […]
