In this post I have explained a simple configuration which can be used as a automatic changeover circuit for switching AC grid mains to generator mains, during power failures or outages. The explained circuit will effectively switch the connected appliances to the generator mains during power failure however it won’t be able to switch start the generator automatically, […]
Newly Updated Circuit Projects:
Emergency Generator Circuit Power Distribution
In this post I have explained a twin generator network system to be used for two separate houses during power failure and through automatic changeover.The idea was suggested by Mr. Ahmad. The Circuit Idea and Objective Thank you for posting the new and useful circuits. I am one of interesting in your website. This work […]
50V 3-Phase BLDC Motor Driver
This yet another versatile 3-phase driver device in the form of IC L6235 from ST Microelectronics allows you to drive a 50V 3-phase BLDC motor with extreme efficiency.The chip also includes all the required protection features built-in, along with an easy to configure external speed control stage. How the IC L6235 BLDC Driver Works The IC […]
Calculator to Design a High Power 3kW PFC (Power Factor Correction) Circuit
In this post I will explain how to use this active PFC calculator for calculating high current, high PFC designs. In our example we will be using 230 VAC input and 3 kW output and Vout equal to around 390 V, and we will try to see how each resistor and capacitor gets calculated in […]
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 […]
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 […]
