Introduction to PCB Layout Principles13 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 Applications13 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 Relays10 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 Types06 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 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.
NPN Transistors and PNP Transistors29 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.
PMIC: Basic Types and Applications [Video]27 October 2020
PMIC (Power Management IC) is used to manage power devices in the host system and is commonly used in cell phones and various mobile terminal devices.
Basic Introduction to Digital Filter [Video]23 October 2020
A Digital filter is an algorithm or device composed of a digital multiplier, adder, and delay unit. The function of the digital filter is to perform arithmetic processing on the digital code of the input discrete signal to achieve the purpose of changing the signal spectrum. The method of the digital filter to filter the signal is: use a digital computer to process the digital signal, and the processing is to calculate according to the pre-programmed program.
What is an Encoder?20 October 2020
An encoder is a device that compiles and converts a signal (such as a bitstream) or data into a signal form that can be used for communication, transmission, and storage. The encoder converts angular displacement or linear displacement into electrical signals.
