How to Use an External Hard Drive?24 June 2021
The external hard drive is a compact and portable hard drive storage which can be plugged in or unplugged at any time. It mainly uses USB or IEEE1394 interfaces. It can transmit data with the system at a higher speed. The IEEE 1394 interface transfer rate is 50-100 MB/s.
Filter Circuit: Types, Characteristics and Principles01 December 2021
The rectifier circuit output voltage is a one-way voltage and cannot be used directly on the electronic circuit. Therefore, it is possible to filter the output voltage, eliminate the AC component in the voltage, and use it to the electronic circuit after DC. In the filter circuit, a device that has special impedance characteristics of AC is mainly used, such as a capacitor, inductor. This article will analyze the various forms of filtering circuits.
Introduction to Step-down Transformers14 October 2020
The step-down transformer is a transformer that converts the higher voltage at the input terminal into an ideal low voltage output, so as to achieve the purpose of step-down. The step-down transformer is a very important equipment in the power transmission and transformation system. Its normal operation not only relates to its own safety and reliable power supply for users, but also directly affects the stability of the power system...
VRAM (Video RAM) Explained03 June 2021
VRAM (video RAM), also known as a frame buffer, is used to store the rendering data processed or about to be extracted by the graphics chip. Like computer memory, VRAM is a component used to store graphics information to be processed.
How does Lidar Work?20 April 2021
Lidar or LiDAR is an abbreviation for Light Detection and Ranging. Lidar is a radar that uses a laser as a radiation source. Lidar is the product of a combination of laser technology and radar technology.
Introduction to Distribution Transformer24 February 2021
Often known as a common kind of isolation transformer is a distribution transformer. The key purpose of this transformer is to adjust the high voltage to the standard voltage to be used in electrical power delivery, such as 240/120 V. There are distinct types of transformers available in the delivery chain, such as single phase, 3-phase, underground, pad-mounted, pole-mounted transformers.
Top 10 Technology Trends in the Global Semiconductor Industry in 202208 January 2022
This article summarizes and analyzes the top 10 technology trends that will emerge or develop at a high rate in the global semiconductor industry in 2022.
Inductance Basis: Definition, Structure and Applications18 April 2022
Hello everyone, I am Rose. Today I will introduce inductance to you. Inductance is a property of a closed loop and a physical quantity. It is a circuit parameter that describes the induced electromotive force effect in this coil or in another coil due to changes in coil current. Inductance is a general term for self-inductance and mutual inductance. A device that provides an inductance is called an inductor.
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 Bandstop Filter28 January 2021
There are numerous filter types, including high-pass filters, low-pass filters, bandpass filters, and filters for bandstops. The high-pass filter only allows frequencies greater than the cut-off frequency, and the low-pass filter allows frequencies smaller than the cut-off frequencies. A specific band of frequencies will be permitted by the bandpass filter and a band stop filter will reject a specific band of frequencies. An overview of the bandstop filter is discussed in this article.
How to Generate Negative Voltage: 5V to -5V Circuit Analysis & Schemes05 January 2026
Hello everyone, I am Rose. Welcome to the new post today. Today I will introduce negative voltage to you. Including its definition, how it was generated and its meaning.
Introduction to AC motor05 March 2021
The motor which uses an electromagnetic induction phänomen to convert the alternative current into mechanical power is called an AC motor. An alternating current drives this motor. Two main components of the AC motors include the stator and the rotor. The stator is the motor's permanent component, and the rotor is the revolving part of the motor. The AC motor can be single or 3-phase.
