In this post I will show how to construct a modified sine wave inverter using Arduino. We will explore the methodology of the proposed sine wave inverter and finally, we will take a look at simulated output of this inverter. By Difference Between Squarewave and Modified Squarewave Inverter Inverters saved us from short term power […]
Newly Updated Circuit Projects:
Automatic Inverter Fan Switch ON while Charging and Inverting Modes
In this post I have explained a simple method of automatically switching ON an inverter fan whenever the unit is operating in the charging mode or inverter mode, in order to ensure optimum cooling of the internal power devices. The idea was requested by Mr. Sudip Bepary. Circuit Objectives and Requirements I have just bought […]
500 Watt Inverter Circuit with Battery Charger
In this post we will comprehensively discuss how to build a 500 watt inverter circuit with an integrated automatic battery charger stage. Further in the article we will also learn how to upgrade the system for higher loads and how to enhance ot into a pure sine wave version. This 500 watt power inverter will […]
Morse Code Flasher Circuit for Lighthouse
In this post I have explained a simple morse code lamp flasher circuit which may be used for model lighthouse signalling applications. The idea was requested by Mr. Frank Gardner. Technical Specifications I am in need of a unique flashing circuit. I have built several exact scale models of the light house at Yerba Buena […]
LiFi Internet Transmitter Circuit – USB Signal Transfer through LED
In this post I have explained how to transmit Internet data through LiFi using a class D amplifier as the transmitter and an ordinary audio amplifier circuit as the receiver. How Li-Fi Concept Works If you are wondering how a LiFi concept could be used for transmitting USB data, this article will provide with all […]
Sine-Cosine Waveform Generator Circuit
The circuit discussed below is designed to generate precision sine and cosine waveforms, which are perfectly identical with their dimensions, but are 90° out of phase. There are a variety of applications which often demand a couple of sinewave frequencies which are of the identical frequency, but 90° out of phase. Simply put, a sine […]
