How to Make a 3 Phase VFD Circuit
The presented 3 phase VFD circuit (designed by me) can be used for controlling the speed of any three phase brushed AC motor or even a brushless AC motor. The idea was requested by Mr. Tom Using the VFD The proposed 3-phase VFD circuit can be universally applied for most 3-phase AC motors where the […]
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 […]
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 […]
