12V 1A Power Supply Circuit Design using VIPer22A Switched-mode power supply circuits (SMPS) are most often required in many electronic designs to convert the AC mains voltage to a suitable level of DC voltage for the device to operate. This type of AC-DC converter takes in the 230V/110V AC mains voltage as input and converts it to low-level DC voltage by switching it, hence the name switch-mode power supply. We have… |

All About Transformer Protection and Transformer Protection Circuits Transformer protection is crucial as transformers are one of the most critical and expensive components of any distribution system. It is an enclosed static device usually drenched in oil, and hence, faults occurring in it are limited. But the effect of a rare fault can be hazardous for the transformer, and the long lead time for repair and replacement of transformers makes… |

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… |

Current Divider Circuits Explained with Formula and Practical Hardware When designing an electronic circuit, there are lots of situations when a circuit requires different values of voltage and current sources. For example, when setting the preset voltage for an Op-Amp, it is very common to use a potential divider circuit to obtain the required voltage values. But what if we need a specific value of current? Similar to the voltage divider,… |

Understanding Dot Convention in Transformers From large power stations to compact SMPS circuits, transformers can be found almost everywhere. Though there are many types of transformers and their exact working differs based on the application, the basic working of the Transformer remains the same. When examining transformer circuit schematics, you'll notice "dot" symbols placed on transformer windings. These dots… |

Design a Simple Constant Current Sink Circuit using Op-Amp Current Source and Current sink are two major terms used in electronics design, these two terms dictate how much current can leave or enter a terminal. For example, the sink and source current of a typical 8051 Microcontroller digital output pin is 1.6mA and 60uA respectively. Meaning the pin can deliver (source) up to 60uA when made High and can receive (sink) up to 1.6mA… |

Design a Voltage Controlled Current Source Circuit using Op-Amp In a voltage-controlled current source circuit, as the name implies, a small amount of voltage across the input will proportionally control the current flow across the output loads. This current source circuit using an op amp is commonly used in electronics to drive current-controlled devices like BJT, SCR, etc. We know that in a BJT, the current flowing through the base of… |
