1. What is IGBT? IGBT stands for "Insulated Gate Bipolar Transistor". It is a composite device composed of MOSFET and bipolar transistors, combining the advantages of both types of power transistors. IGBTs come in two types: N-channel and P-channel, with N-channel being the mainstream product currently. The following Figure 1 shows an N-channel I

Electronic components in circuits mainly include diodes, transistors, thyristors, and field-effect transistors, among which diodes and transistors are the most commonly used. Correctly determining the quality of diodes and transistors is one of the basic skills electricians should master. 1. Measurement of Diodes 1. Usually, use the Rx100Ω range or Rx1kΩ range of a multimeter to measure diodes with lower withstand voltage and smaller current. 2. When measuring the forward and reverse resistance of a 2AP9 type diode with a multimeter's resistance range, the Rx100Ω range should be selected. If the forward resistance value of the diode is between tens to hundreds of ohms, and the reverse...

"Cloud computing" (cloud computing) is believed to be known to everyone. Simply put, it involves placing resources on a virtual network cloud, and users can access and use them via the internet.

So what is edge computing? How does it differ from cloud computing?
First, let's look at Forbes' predictions for "edge computing" trends in 2024:
Edge Computing Everywhere
Edge computing is a cloud-

Why are wafers round?
Because the manufacturing process determines they are round. Purified high-purity polysilicon grows on a seed crystal by rotating. After the polysilicon is melted and placed in a quartz crucible, the seed crystal is placed in the crucible, rotated at a constant speed and pulled upward, then the molten silicon grows along the seed crystal into a cylindrical silicon ingot. This method is the CZ method (Czochralski) still in use today, also called the single crystal pulling method. As shown below:
 

Surge Protective Devices (SPD) are important devices used to protect electronic equipment from power surges or transient voltage effects. When we purchase SPD-related products, we find an important parameter behind their lightning protection capability discharge current KA —— 8/20us or 10/350us. What do these two parameters actually mean? Let's explore together.
 
1. Lightning Waveforms
8/20us and 10/350us both represent data on the time variation of impact pulse current, where 8/20us is a typical lightning breakdown of the ground (

The automotive three electric systems refer to the three core components of electric vehicles, namely the motor, battery, and electronic control system. Together, they form the power system of electric vehicles, responsible for driving the vehicle.1. Analysis Explanation
Motor
The motor is the power source of electric vehicles, responsible for converting electrical energy into mechanical energy to drive the wheels. There are many types of motors, such as DC motors, AC asynchronous motors, permanent magnet synchronous motors, etc. Among them, permanent magnet synchronous motors are widely used in electric vehicles due to their high efficiency, high power density, and good speed regulation performance.

Electromagnetic Compatibility (EMC) Standards and Testing Content 
 


Internationally, the development of electromagnetic compatibility standards has a history of over 70 years. Initially, to protect radio communication and broadcasting, the International Special Committee on Radio Interference (CISPR) proposed relevant electromagnetic interference emission limits and measurement methods for various electrical equipment and systems. By the 1960s-1970s, due to the miniaturization, digitization, and low power consumption of electronic and electrical equipment, people began to consider the anti-interference capability of equipment. Major international standardization organizations and national government agencies...

MOSFET is a basic component in electronic manufacturing, but when facing MOSFETs with different packages, characteristics, and brands, how to choose? Is there a worry-free and labor-saving screening method?


Choosing the right MOSFET can well control production and manufacturing costs, and most importantly, match the product with the most appropriate component. This will fully play its "screw" role in the future use of the product, ensuring the most efficient, stable, and durable application of the equipment.
 
So when faced with a dazzling array of...
