Power semiconductor devices refer to electronic devices that can directly achieve electrical energy conversion or circuit control in main circuits, mainly used for power conversion, including rectification, inversion, DC chopping, as well as AC power control, frequency conversion, or phase change. Unlike other types of semiconductors, power semiconductors can withstand high voltage and large current, usually operating in switching state, and are the core of electrical energy conversion and circuit control, playing a key role in efficient generation, transmission, conversion, storage, and control of electrical energy.
Power semiconductor devices can be divided into bipolar power semiconductors and unipolar power semiconductor devices according to carrier type. Bipolar power semiconductor devices include...

What is a Semiconductor?









        "Semiconductor" is a substance whose characteristics are between "conductor" and "insulator", the former conducting electricity like metal, the latter almost not conducting electricity. The ease of current flow is related to the electrical...

Silicon wafers are the infrastructure of China's "core" and one of the cornerstones of China's new infrastructure.
In the semiconductor industry chain, silicon wafers, as an important core material in chip manufacturing, play a key role in chip manufacturing. The quality, size, cost, etc., of silicon wafers directly affect chip performance and competitiveness.
At the historical intersection point of China's economic transformation cycle and global technological innovation cycle overlapping, China's semiconductor silicon wafer market has become the fastest-growing market globally. According to SEMI (International Semiconductor Industry Association) statistics, China's semiconductor silicon wafer sales reached 16...

We often see a small cylindrical bulge on data cables or power cables of laptops, digital cameras, etc., which actually contains a ferrite magnetic ring clamp filter. This is the result of electromagnetic compatibility anechoic chamber testing.
　　 If noise reduction is handled well during electronic product development, this filter is not needed. However, if the product itself has been developed and problems are still found during testing, the simplest method is to add a filter. One reason is that during data transmission, cables also radiate electromagnetic waves.
　　
　　 The demand for anechoic chambers is growing year by year
　　
　　 The earliest anechoic chambers...

IGBT is the abbreviation of "Insulated Gate Bipolar Transistor", also known as Insulated Gate Bipolar Transistor. IGBT is classified in the field of power semiconductor components and transistors.


Characteristics of Power Semiconductor Components
In addition to IGBT, representative products in power semiconductor components (transistor field) include MOSFET, BIPOLAR, etc., which are mainly used as semiconductor switches. According to their respective supported switching speeds, BIPOLAR is suitable for...

      The impact of lightning strikes and surges is an often overlooked important risk factor. Lack of preventive measures can lead to serious consequences, such as fires, important equipment shutdowns, and misoperations. Therefore, lightning and surge protection measures are an important component of safety schemes, because modern society is a large whole working together and cooperating.

      Lightning and surge protection should be considered in the early stages of project planning, as implementation is much easier in the early stages. Later modifications will be difficult to achieve...

ISO指International organization for Standardization（国际标准化组织），是总部设在瑞士日内瓦的非政府机构。制定了许多国际标准（IS：International Standard），估计很多人都知道ISO 9001（质量管理体系）和ISO 14001（环境管理体系）等。ISO制定的汽车领域的电气/电子系统的“功能安全”国际标准就

AC/DC converters have the function of converting AC (alternating current voltage) to DC (direct current voltage).
Why are AC/DC converters needed?
Why are AC/DC converters needed? That's because the voltage received by residential homes and buildings is 100V or 200V AC voltage. However, most electrical appliances we use operate on 5V or 3.3V DC voltage. That is to say, if AC voltage is not converted to DC voltage, electrical appliances cannot operate.



Among them, there are also products such as motors and light bulbs that can be driven by AC voltage, but the control circuits of motors and microcontrollers...
