60 Watt Amplifier Circuit
The circuit of a 60 watt power amplifier is shown in the below figure. It’s design layout is simple and very conventional. It has a completely symmetrical pattern which has one pole frequency compensation, yet some uncommon methods have been employed in order to keep the number of parts less. To start with, the configuration […]
22 Watt Stereo Amplifier Circuit using 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 […]
How to Build a 100 Watt, Pure Sine Wave Inverter
The circuit provided in this article shows you a simple way of building a useful liitle inverter that’s easy to build and yet provides the features of a pure sine wave inverter. The circuit can be easily modified for getting higher outputs. Introduction Let’s begin the discussion about how to build a 120 Volt, 100 […]
5 Easy 1 Watt LED Driver Circuits
In this post I have explained about a few easy to build, compact 1 watt LED bulb circuits. The first circuit is SMPS based, the second design uses a capacitive power supply, while the remaining concepts show how to used a DC source to illuminate a 1 watt LED. Warning: Many of the circuits I […]
