Understanding Amplifier Circuits

In general, an amplifier can be defined as a circuit designed to boost an applied low power input signal into a high power output signal, as per the specified rating of the components. Although, the basic function remains the same, amplifiers could be classified into different categories depending on their design and configurations. Circuits for … Read moreUnderstanding Amplifier Circuits

Triac Phase Control using PWM Time Proportional

A triac phase control using a PWM circuit can be useful only if it’s implemented using a time-proportional format, otherwise the response could be haphazard and inefficient. In a few of of my earlier articles as given below: Simple Remote Controlled Fan Regulator Circuit Push Button Fan Regulator with Display Circuit Dimmer Circuit for LED … Read moreTriac Phase Control using PWM Time Proportional

How to Add a Dimmer Facility to a LED Bulb

In this article we learn how to make a dimmer circuit for LEDs bulbs and LED tubes which are intended to be operated with mains 220V or 120V. How LED Bulbs Work We know that our ceiling fans and incandescent bulbs can be easily controlled using triac dimmer switches, and we are quite used to … Read moreHow to Add a Dimmer Facility to a LED Bulb

How to Make a Zero Crossing Detector Circuit

Making a zero crossing detector circuit is actually very easy and it could be effectively applied for protecting sensitive electronic equipment against mains switch ON surges. A zero crossing detector circuit is mainly used for protecting electronic devices from switch ON surges by ensuring that during power switch ON the mains phase always “enters’ the … Read moreHow to Make a Zero Crossing Detector Circuit

3 Phase Induction Motor Speed Controller Circuit

In this post we discuss 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 stages … Read more3 Phase Induction Motor Speed Controller Circuit
