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 […]

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 […]
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 […]
Single Phase Variable Frequency Drive VFD Circuit
In this post I have explained a single phase variable frequency drive circuit or a VFD circuit for controlling AC motor sped without affecting their operational specifications. What is a VFD Motors and other similar inductive loads specifically do not “like” operating with frequencies that might be not within their manufacturing specs, and tend to […]
3 Phase Induction Motor Speed Controller Circuit
In this post I have explained the making of a simple 3 phase induction motor speed controller circuit, which can be also applied for a single phase induction motor or literally for any type of AC motor. When it comes to controlling the speed of induction motors, normally matrix converters are employed, involving many complex […]
3 Phase Brushless (BLDC) Motor Driver Circuit
In this post I have explained how to make a simple 3 phase brushless DC motor driver circuit. The circuit employs the popular IRS2330 3-phase driver IC The presented idea looks simple since most of the technicalities is taken care of efficiently by the IC itself, it’s all about connecting the relevant pinouts with the […]
