Diodes Tutorial: How to Test Diodes?22 October 2025
A diode is an electronic device made of semiconductor materials. The diode is one of the earliest semiconductor devices, and it is widely used, especially in various electronic circuits.
How does an Inverter Work?06 April 2021
The inverter is a converter that converts DC electric energy into constant frequency and constant voltage AC or Frequency and voltage modulation AC. It is composed of an inverter bridge, control logic, and filter circuit. Inverters are widely used in air conditioners, home theaters, electric grinding wheels, power tools, DVDs, VCD, computers, TVs, washing machines, range hoods, refrigerators, video recorders, massagers, fans, lighting, etc.
VRLA Battery: Working Principle, Capacity and Maintenance12 March 2021
VRLA batteries, which means Valve Regulated Lead Acid Battery was born in the 1970s. By 1975, a considerable scale of production had been formed in some developed countries, and industrialization was soon formed and put on the market in large quantities. Although this battery is also a lead-acid battery, it has many advantages compared with the original lead-acid battery, and is very popular with users, especially for those who need to install battery supporting equipment together (or a workshop). , Such as UPS, telecommunications equipment, mobile communication equipment, computers, motorcycles, etc.
Characteristics, Types, and Functions of Electrolytic Capacitors17 October 2025
Inside the electrolytic capacitor is an electrolyte material that stores electric charge. It has positive and negative polarity, which is similar to a battery, and it cannot be reversed. The positive electrode is a metal substrate with an oxide film. The negative electrode is connected to the electrolyte (solid and non-solid) through the metal electrode plate.
Random Access Memory: Definition, Types and Working29 August 2020
Random Access Memory (RAM), also called main memory, is an internal memory that directly exchanges data with the CPU. It can read and write at any time (except when refreshing), and and is usually used as a temporary data storage medium for the operating system or other running programs. The biggest difference between it and ROM is the volatility of data, that is, the stored data of RAM will be lost once the power is off.
Basic Introduction to Power Amplifier09 January 2026
Power amplifier refers to an amplifier that can generate the maximum power output to drive a certain load (such as a speaker) under a given distortion rate. The power amplifier plays a pivotal role of "organization and coordination" in the entire audio system, and to a certain extent dominates whether the entire system can provide good sound quality output.
A Guide to Semiconductor IP Core18 January 2022
The IP to be introduced in this article is both a technical term and a commodity. It brings together the wisdom of chip designers and has the attributes of a commodity and intellectual property, which can be promoted, sold, and applied. Therefore, there are scientific and commercial activities such as IP development, IP trading and IP reuse in the semiconductor industry, and there are also some companies that are named as IP vendors and IP providers.
Introduction to Lead Acid Battery: Construction, Working Principle and Types04 March 2021
The rechargeable and secondary batteries category includes lead acid batteries. Despite the battery's low energy-to-volume and energy-to-weight ratios, it can deliver higher surge currents. This refers to the fact that lead acid cells have a high power-to-weight ratio.
What is an Accelerometer: Definition, Types and Applications02 April 2022
Hello everyone, I am Rose. Today I want to introduce the accelerometer to you. An accelerometer is an instrument that measures the linear acceleration of a carrier. An accelerometer consists of a proof mass (also called a sensitive mass), support, a potentiometer, a spring, a damper, and a housing. Among them, the accelerometer for measuring aircraft overload is one of the earliest aircraft instruments to be used.
What is a Capacitive Sensor?31 October 2025
Capacitive sensors use various types of capacitors as sensing elements. It is a conversion device that converts the measured physical or mechanical quantities into changes in capacitance which is actually a capacitor with variable parameters. Capacitive sensors are widely used for measurement of displacement, angle, vibration, speed, pressure, composition analysis, medium characteristics, etc.
Metal Oxide Varistor: Specifications, Working and Construction26 January 2021
MOV is essentially a variable resistor, but MOVs can adjust its resistance depending on the applied voltage, unlike potentiometers. If the voltage through it raises the resistance decreases and vice versa. This property is helpful in shielding the circuits from high voltage surges, so they are often used in an electrical network as surge protectors.
Buffer Amplifier | Operating Principle, Advantages, and Applications21 July 2025
This guide will talk in detail about the buffer amplifier to clarify all your concepts around its working principle and applications.
