Bridge Rectifier: Functions, Circuits and Applications03 November 2020
Bridge rectifiers are the most commonly used circuits for rectifying AC to DC using the single conductance of a diode. A bridge rectifier consists of four rectifier silicon chips connected by a bridge and encapsulated in insulating plastic. There is a zinc metal shell over an insulating layer to enhance heat dissipation in a high power bridge rectifier.
DVI Connector: Types, Advantages, Distiguishment And Development18 November 2020
A DVI connector, that is, digital video interface connector, is an interface standard launched in 1999 by the DDWG (Digital Display Working Group) formed by Silicon Image, Intel, Compaq, IBM, HP, NEC, Fujitsu and other companies.
Introduction to Pi Filter19 February 2021
A Pi filter is a type of filter with a two-port, three-terminal block consisting of three elements with two terminals in each element: the first element is connected to the GND terminal via i/p, the second terminals are connected to the terminals from i/p to o/p and the third element is connected to the terminals from o/p to GND. The circuit model is going to be like a 'Pi' symbol. Capacitors and one inductor are the elements used in the circuit.
Introduction to Semiconductor Devices17 October 2025
Semiconductor devices are electronic devices with conductivity between a good conductor and an insulator. It uses the special electrical characteristics of semiconductor materials to accomplish specific functions such as generate, control, receive, transform, and amplify signals, and convert energy.
What are Laser Diodes?20 October 2025
Laser diodes include single heterojunction (SH), double heterojunction (DH), and quantum well (QW) laser diodes. The quantum well laser diode has the advantages of low threshold current and high output power, which is the mainstream product in the market. Compared with optical maser, laser diodes have the advantages of high efficiency, small size, and long life, but their output power is small (generally less than 2mW), linearity and monochromaticity are poor, limiting their applications in cable television systems for not able to transmit multi-channel, high-performance analog signals. In the feedback module of the bidirectional optical receiver, the uplink transmission generally uses a quantum well laser diode as a light source.
How do Transistors Work?10 August 2020
A transistor is a kind of semiconductor device that controls current. Its function is to amplify the weak signal into an electrical signal with a larger amplitude value, and it is also used as a contactless switch.
What is Color Ring Inductor? How to Read Inductor Color Code?01 April 2025
Hello everyone, I am Rose. Today I will introduce color ring inductor to you. A color ring inductor, also known as a color code inductor or a color ring inductor, is a self-inducting component. Together with a capacitor, the inductance coil (color ring inductance) frequently creates a resonant and filter circuit in the circuit.
Introduction to EPROM and EEPROM08 January 2026
EPROM (Erasable Programmable Read-Only Memory) is a kind of ROM memory with erasable function and can be reprogrammed after erasing. Before writing, the contents inside must be irradiated with ultraviolet rays on the transparent window on its IC card to clear it. EEPROM (Electrically Erasable Programmable Read-Only Memory), a memory chip that does not lose data after power failure. EEPROM can erase the existing information and reprogram it on the computer or special equipment.
What is Regulated Power Supply?08 January 2021
Regulated power supply is an electronic device that can provide stable AC or DC power to the load, including AC regulated power supply and DC regulated power supply.
What is Electronic Ballast?28 September 2020
Electronic Ballast is a kind of ballast, which uses electronic technology to drive the electric light source to produce the required lighting. Corresponding to it is the inductive ballast. More and more modern fluorescent lamps use electronic ballasts, which are light and compact, and people can even integrate electronic ballasts with lamps.
Introduction to Servo System08 September 2021
Servo system is a product developed on the basis of frequency conversion technology. It is an automatic control system that takes a mechanical position or angle as the control object.
Introduction to Photonic Integrated Circuits and PIC Technology22 October 2025
The concept of the photonic integrated circuit is similar to the concept of electronic integrated circuits. However, electronic integrated circuits integrate transistors, capacitors, resistors, and other electronic devices, while PIC integrates various optical devices or optoelectronic devices, such as lasers, electro-optical modulators, photodetectors, optical attenuators, optical multiplexers/demultiplexers, and optical amplifiers.
