Design and Implementation of High Frequency Inverter for Printer Based on IR2110
13 April 2022
Hello everyone, I am Rose. Welcome to the new post today.In this article, the design of an independent inverter power supply based on SPWM technology is completed by combining the principle of the inverter circuit with the single-chip technology.
How to Generate Negative Voltage: 5V to -5V Circuit Analysis & Schemes
05 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.
A Guide to AVR Microcontroller [PDF]
15 October 2025
AVR microcontroller is an enhanced RISC (Reduced Instruction Set CPU) high-speed 8-bit microcontroller with built-in Flash developed by ATMEL in 1997.
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.
Introduction to Top Sensor Manufacturers in the World
15 February 2022
The modern industrial system cannot be separated from sensors. In this article, we will introduce you to 10 world-renowned sensor companies.
VRAM (Video RAM) Explained
03 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.
Filter Circuit: Types, Characteristics and Principles
01 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 TFT Displays
29 August 2020
TFT Display is a thin film transistor type liquid crystal display. TFT liquid crystal is equipped with a semiconductor switch for each pixel, and each pixel can be directly controlled by dot pulses. So each node is relatively independent and can be continuously controlled, which not only improves the response speed of the display screen, but also allows precise control of displaying color gradation, so the color of TFT liquid crystal is truer.
Introduction to Flash Memory
31 October 2025
Flash memory is a non-volatile computer memory storage medium that allows multiple erases or writes during operation. This technology is mainly used for general data storage, as well as the exchange and transmission of data between computers and other digital products, such as memory cards and USB flash drives.
Inductance Basis: Definition, Structure and Applications
18 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.
What is RF Filter?
09 December 2021
Hello, I am Rose Welcome to the new post today. The radio frequency filter is a filter circuit made up of capacitors, inductors, and resistors that is used to filter the signal frequency in communication channels. The filter allows signals that meet a specific frequency to pass while suppressing unwanted frequency signals.
