Thyristor Commutation Techniques To turn on a Thyristor, there are various triggering methods in which a trigger pulse is applied at its Gate terminal. Similarly, there are various techniques to turn off a Thyristor; these techniques are called Thyristor Commutation Techniques. It can be done by bringing the Thyristor back into the forward blocking state from the forward conduction state. To bring the… |

Overvoltage Protection Circuit Protection circuits, like reverse polarity protection, short-circuit protection, and over/under voltage protection, are used to protect any electronic appliance or circuit from any sudden mishap. Generally fuse or MCB is used for overvoltage protection. Here in this circuit, we will build a simple overvoltage protection circuit without using a fuse. … |

How to Build FM Transmitter Circuit One of the cool projects I always wanted to build is an FM transmitter with a good range. I have always been fascinated by some of the applications of the transmitter, especially when I was younger and, like everyone else, spent most of my time imagining how cool it would be to have some of the equipment and devices used in spy movies. So recently, while going over one of my… |

Introduction to Bit Banging: SPI communication via Bit Banging Communication Interfaces are one of the factors that are considered when selecting a microcontroller to be used for a project. The designer ensures that the microcontroller being selected has all the interfaces required to communicate with all the other components to be used for the product. The existence of some of these interfaces, like SPI and I2C on microcontrollers,… |

Asynchronous Counter An asynchronous counter (or ripple counter) is a sequential digital circuit in which the outputs of flip-flops are connected in series, so that the output of one flip-flop serves as the clock input to the next stage. Not all flip-flops may change state at the same time as synchronous counters, so asynchronous counters are easier to design but may experience propagation delays. Table of… |

Voltage Regulator Circuits Voltage Regulator, as the name suggests, is a circuit that is used to regulate the voltage. Regulated voltage is a smooth supply of voltage, free from any noise or disturbance. The output from the voltage regulator is independent of load current, temperature, and AC line variation. Engineers can create reliable power supply systems with the aid of these voltage… |

Voltage Controlled Oscillator (VCO) Most of the consumer electronic devices around us, such as mobile phones, TVs, Radios, and MP3 players, are a combination of Digital and Analogue electronics. Wherever wireless transmission/reception, or audio signals are involved in an electronic design, we will need periodic oscillating electronic signals. These signals are called Oscillating signals and are very useful in… |

RC, RL and RLC Circuits The entire range of electronic components can be divided into two broad categories: active components and passive components. The Passive components include the Resistor (R), the Capacitor (C) and the Inductor (L). These are the three most used components in electronics circuits, and you will find them in almost every application circuit. These three components together in… |

Cycloconverters – Types, Working and Applications Power supplies can be classified into two broad categories: AC power supply and DC power supply. Since only AC power can be generated economically, most electrical machines run on AC power. However, the standard voltage and frequency from generating stations may not suit certain industrial machines. This is where power electronic converters like inverters and cycloconverters… |

What is Thyristor and How it works? In general, Thyristors are also switching devices similar to transistors. As we already discussed, Transistors are the tiny electronic components that changed the world. Today we can find them in every electronic device like TVs, mobiles, laptops, calculators, earphones, etc. They are adaptable and versatile, but that doesn’t mean that they can be used in every… |
