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 […]
Grid and 3-Phase
Single Phase Voltage from Three Phase Voltage Source
In this post I have explained a simple relay changeover circuit for extracting single phase AC from a three phase AC source irrespective of the condition whether all the three phases are present or not. The circuit was requested by Mr. Biannz. Technical Specifications hi sir please i need something I’ve been searching everywhere but not avail […]
2 Simple Automatic Transfer Switch (ATS) Circuits
In this article we investigate an ATS circuit for initiating an automatic changeover from mains supply to generator supply through many intermediate transfer stages which involves activating the fuel valve, choke valve and the generator starter. The circuit was requested by Mr. Hari, and another dedicated reader from this blog. Requirement for 5kva LPG Generator […]
Simple 3 Phase Inverter Circuit
In this post I have explained how to make a 3 phase inverter circuit which can be used in conjunction with any ordinary single phase square wave inverter circuit. The circuit was requested by one of the interested readers of this blog. UPDATE: Looking for an Arduino based design? You may find this one useful: Arduino 3 […]
Electronic Load Controller (ELC) Circuit
In this post I have explained a simple electronic load controller or governor circuit which automatically regulates and controls the rotational speed of a hydro-electric generator system by adding or deducting an array of dummy loads. The procedure ensures a stabilized voltage and frequency output for the user. The idea was requested by Mr. Aponso […]
Arduino 3 Phase Inverter Circuit with Code
An Arduino three phase inverter is a circuit which produces a 3 phase AC output through a programmed Arduino based oscillator. In this post I have explained how to make a simple microprocessor Arduino based 3 phase inverter circuit which could be upgraded as per user preference for operating a given 3 phase load. We […]
