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.
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.
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.

Power Transformer Basics and Operation Cautions
16 October 2020
A power transformer is a static electrical device that is used to change a certain value of AC voltage (current) into another or several voltages (current) with the same frequency. It is a necessary equipment for power transmission and distribution and power distribution for power users...
What is Sequential Logic?
15 October 2020
Sequential logic is an important part of digital logic circuit, which is mainly composed of storage circuit and combinational logic circuit. Sequential logic is also called sequential logic circuit. It is different from other circuits that we are familiar with. Its output state at any time is determined by the input signal and the original state of the circuit at that time, and its state is mainly memorized and represented by the storage circuit.
