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 […]

220V/120V LED String Light Circuit using a Single Capacitor
In this post I have explained how to make a LED string light which can be operated from 220V mains through a single inexpensive PPC capacitor. The idea was requested by Mr. Basit Momin.WE STRICTLY CAUTION YOU THAT YOU BUILD THIS CIRCUIT ONLY IF YOU ARE AWARE OF THE DANGERS OF MAINS AC AND KNOW […]
100 Watt Power Amplifier Circuit Diagram using a Single IC TDA7294
Building a power hi-fi amplifier with MOS transistors requires the implementation of a relatively large number of components because, at the level of power stages, the connection between the bipolar transistors that make up the input stages and the MOS transistors of the output stages is far from simple. Fortunately, there is an elegant solution […]
100 to 160 watt Power Amplifier Circuit Diagram using a Single IC OPA541
For anyone who is searching for an audio amplifier with massive output power in the order of 100 watt to 200 watts, using an absolute minimum parts count, this particular circuit will accomplish it. How the Circuit Works The IC OPA541 from Burr-Brown is a power opamp is specially designed to work from power supplies […]
Automatic Door Controller Circuit Diagram using a Single Push-Button
This door controller circuit works in this way: Initially the door is in the closed state. When a push button is pressed, the door begins opening until it reaches the end of the course. When it reaches the end, it automatically reverses its direction and now the door begins closing. It keeps moving until it […]
Single Phase AC to Three Phase AC Converter Circuit
In this post I have explained an interesting single phase AC to 3 phase AC circuit. The idea was requested by Mr. Sachin Sinalkar. Technical Specifications Hi dear sir, is there any way by which we can convert single phase 230V supply into three phase. i had try to ask question on your web site […]
