How to Convert 3 phase AC to Single phase AC
In this post I have explained how to convert 3 phase AC to single phase AC through a special bridge rectifier at any desired voltage. The idea was requested by Mr. Chaquito Technical Specifications You have a very nice page and I find it really good, If been looking for a 380V 3ph converter to […]
Simple Soil Moisture Tester Circuit with a Single IC 741
A very simple mud or soil moisture tester circuit can be built by using a single opamp and a few passive components, I have explained the details through the following article. Circuit Objective After water and sunlight the earth or the soil is the next most important natural gift that this planet has provided us […]
Single Phase Preventor Circuit
In this post I have explained a couple simple circuits which when installed will prevent single phase occurrence in a 3 phase system. Introduction We all know that for operating heavy electrical loads three phase power or AC is required in order to make the functioning efficient and viable. However this necessitates the presence of all the three phases […]
Simple FM Radio Circuit Using a Single Transistor
When it comes to making an FM receiver it’s always thought to be a complex design, however the one transistor simple FM receiver circuit explained here simply shows that it isn’t the case after all. Here a single transistor acts as a receiver, demodulator, amplifier to constitute a wonderful tiny FM radio. It’s basically based […]
Single IC Dimmable Ballast Circuit
In this post I have explained a simple 25 to 36 watt ballast circuit which can used for all fluorescent tube applications within the allocated range. The circuit of the proposed electronic fluorescent ballast may be understood through the following discussion: The Preheater Stage The half-bridge stage comprising the two mosfets are triggered by the […]
