230V AC LED Driver Circuit for Powering 2.5Watts LED Light AC LED driver circuits are overly popular due to the advancement of High current white LEDs. We already made a Transformerless LED driver circuit previously, but in that circuit, we used a dedicated LED driver IC like LNK304 to generate 13.6V 150mA of output current to power LEDs. But in this tutorial, we will not use any dedicated driver ICs, but we will make a 2.5 Watt AC… |

Simple Ultrasonic Acoustic Levitation using Arduino and HCSR04 Ultrasonic Sensor It is very exciting to see something floating in the air or free space that is exactly what an anti-gravity project is about. The object (basically a small piece of paper or thermocol) is placed between two ultrasonic transducers which generate acoustic sound waves. The object floats in the air because of these waves which seem to be of anti-gravity. This is not only a cool… |

Half Wave and Full Wave Precision Rectifier Circuit using Op-Amp A rectifier is a circuit that converts alternating current (AC) to Direct current (DC). An alternating current always changes its direction over time, but a direct current flows continuously in one direction. In a typical rectifier circuit, we use diodes to rectify AC to DC. But this rectification method can only be used if the input voltage to the circuit is greater than… |

Positive and Negative Charge Pump Circuit In a previous article, I have shown you how you can build your own switched capacitor voltage converter circuit using the classic industry-standard LMC7660 IC. But oftentimes there are situations when you don't have a specific IC available or the cost of an additional IC is ruining the harmony of your BOM. And this is where our beloved 555 timer IC comes to rescue. That is… |

Build Your Own Guitar Distortion Pedal Circuit Who does not like the rumbling tone of a distorted electric guitar? It is a key part of many important genres of music, especially in blues and rock music genres and is also frequently used in hard rock, metal or the punk music genre. In this project, we will build a basic distortion pedal for guitars using a simple circuit. You can also check out the Arduino Guitar Tuner Circuit if you are… |

Three Phase Inverter Circuit - 120 Degree and 180 Degree Conduction Mode We all know about an inverter - it is a device which converts DC into AC. And we previously learned about Different types of inverters and built a single-phase 12V to 220V inverter. A 3 Phase Inverter converts the DC voltage into a 3 Phase AC supply. Here in this tutorial, we will learn about the Three-Phase Inverter and its working, but before going any further, let… |

High Performance 50mm and 60mm Thyristor/Diode Modules for Drives and UPS applications Infineon Technologies expands its product portfolio of thyristor/diode module with the new Prime Block 50mm modules which feature solder bond technology and 60mm modules pressure contact technology. These Prime Blocks are designed for higher performance when the desired current exceeds 600A for a 60mm footprint or 330A for a 50mm footprint. This avoids the paralleling of… |

Diode Clamper Circuits Previously we learned about Clipper Circuits, which are used to clip off the positive or negative part of the Alternating waveform. Today we will learn about Clamper circuits which are used to clamp the DC level of the output signal without distorting the waveform i.e. they are Level Shifter circuits. It can be designed using capacitor, diode and resistor. The… |

Schottky Diode – Characteristics, Parameters and Applications A diode is one of the basic components that are commonly used in electronic circuit designs; it can be commonly found in rectifiers, clippers, clampers and many other commonly used circuits. It is a two-terminal semiconductor device that allows the current flow in only one direction, that is, from Anode to Cathode (+ to -) and blocks the current flow in the reverse direction… |

Diode Clipper Circuits: Design & Demonstration As the name suggests, Clipper circuit is used to “clip” a portion of input signal without distorting the remaining part of the waveform. It is a wave shaping circuit. This can be very useful in the circuits where the input signal attains a higher value of voltage than the expected one. These circuits can be implemented in various ways according to the configuration or… |

Mains Power Supply Failure Alarm Circuit Although there are inverters and generators to immediately start the AC power supply whenever there is a power cut but sometime when there is no backup support and we have some critical machines running to perform some important task, it’s a good idea to atleast have an alarm which notify us as soon as power goes off. In this tutorial, we will learn how to make a simple… |
