DVI Connector: Types, Advantages, Distiguishment And Development
18 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.
Classification and Working Principle of Ballast Resistor
18 November 2020
The ballast resistor is connected between the power source and one or more discharge lamps and is mainly used to limit the current of the lamp to a required value. It may include devices that change the supply voltage or frequency and increase the power factor, which can be used alone or together with the starter to provide the necessary conditions for the lamp to start.
Introduction to PCB Layout Principles
13 November 2020
What are the basic principles to be followed in the PCB board layout? How to design a PCB layout with a large number of components? How are electronic components laid out and routed on the circuit board? This article is an explanation of these questions.
Toroidal transformer: Principles, Features, Types and Applications
13 November 2020
Toroidal transformer is a type of electronic transformer, which has been widely used in household appliances and other electronic equipment with high technical requirements. It’s mainly used as a power transformer and isolation transformer, also widely used in computers, medical equipment, telecommunications, instruments and lighting. The toroidal transformer is a competitive electronic transformer for its good output characteristics and anti-interference ability.
Introduction To Different Types Of Relays
10 November 2020
A relay is an electrical control device. It has an interactive relationship between the control system and the controlled system. Usually used in automated control circuits, it is actually an "automatic switch" that uses a small current to control the operation of a large current. Therefore, it plays the role of automatic adjustment, safety protection, and conversion circuit in the circuit.
What is Digital Power Supply?
10 November 2020
The digital power supply is mainly the external characteristics of switching power supply. One is the "communication" function of the digital power supply, the second refers to the "NC" function of the digital power supply, and the third refers to the “monitoring” function of the digital power supply, for example, to temperature and other parameters.
A/D Converter: Basic Principle and Types
06 November 2020
An analog-to-digital converter, or A/D converter, or ADC for short, is usually an electronic component that converts an analog signal into a digital signal. A typical analog-to-digital converter converts an input voltage signal into an output digital signal.
What Is An Intrinsic Semiconductor?
03 November 2020
An intrinsic semiconductor is a single crystal made from a pure semiconductor through a certain process. Intrinsic semiconductors are semiconductors with complete crystal lattices without any impurities. Its conductivity is not affected by any impurities or lattice defects, and is only determined by the nature of the semiconductor material itself.
Bridge Rectifier: Functions, Circuits and Applications
03 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.
An Overview of LPDDR
30 October 2020
LPDDR (Low Power Double Data Rate) SDRAM, a type of DDR SDRAM, also known as mDDR (Mobile DDR SDRAM), is a communication standard developed by the JEDEC Solid State Technology Association for low-power memory. Known for low power consumption and small size, it is specially used for mobile electronic products.
NPN Transistors and PNP Transistors
29 October 2020
NPN and PNP are two types of transistors. Transistors are semiconductor devices made of doped p-type and n-type junctions. This article mainly introduces the differences between this two kinds of transistors, the methods of distinguishing them, and the application of them.
