1051 安森美 IGBT 晶体管

听起来可能很奇怪，但这是真的。
回到金属加工的早期，大约3500年前，一些“明亮的火花”建立了一个融合两个元素表面形成一个单元的过程，焊接诞生了！
“在花费和未经考虑的地球上，城市再次崛起。”Rudyard Kipling
自古以来，由于焊接仍然具有成本效益，可靠和安全，因此对焊接的需求持续增长。
2014年全球焊接产品市场达到近193亿美元，预计到2019年将增长到251亿美元，复合年增长率为5.3％。
建筑和建筑占全球市场的17％以上，随着需求的增长，建筑行业预计将需要越来越多的焊接设备，特别是亚太地区的新建筑和建筑项目以及汽车，能源等行业的需求
，铁路和采矿。
焊接行业最新的创新发展之一是采用变频焊机，与使用重型变压器和整流器的传统焊机相比，采用硅基技术在成本，性能和效率方面具有显着优势。
绝缘栅双极晶体管（IGBT）技术的采用极大地减小了变压器的尺寸和对许多磁性元件的要求，使得逆变焊机的重量更轻，尺寸更小，因此更易于携带。
此外，在输出电流频率较高的情况下，逆变焊机在焊接时会产生更平滑的电弧，同时节能更省电，因为它消耗的电量更少。
完美适用于逆变器焊接应用的新型安森美半导体NGTB25N120S 1200V / 25A IGBT具有坚固且经济的沟槽结构，在要求苛刻的开关应用中提供卓越的性能，提供低导通电压和最小开关损耗。
这些IGBT可以构建一个能够应对高负载电弧的开关电源。
如果焊接的起源和实践如此陈旧以至于它“从方舟中出来”，那么很高兴知道安森美半导体的创新IGBT技术现在可以帮助创造完美的电弧！

It may sound bizarre but it’s true. Going back to the earliest days of metalworking, circa 3500 years ago, some ‘bright spark’ established a process for fusing the surface of two elements to form a single unit and welding was born!
“Out of the spent and unconsidered earth the cities rise again.” Rudyard Kipling
Since those ancient times the demand for welding continues to grow thanks to the fact that it remains cost effective, reliable and safe. The global market for welding products reached nearly $19.3 billion in 2014 and is expected to grow to $25.1 billion by 2019, demonstrating a CAGR of 5.3%. Building and construction accounts for over 17% of the global market and the construction industry is anticipated to require an increasing amount of welding equipment as demand grows, especially with new construction and building projects in Asia Pacific and with demand from industries such as Automotive, Energy, Railways, and Mining.
One of the most recent innovative developments within the welding industry has been the introduction of Inverter Welders which use silicon based technology to bring significant advantages in terms of cost, performance and efficiency over conventional welders that use heavy transformers and rectifiers. The adoption of insulated gate bipolar transistor (IGBT) technology dramatically reduces the size of the transformers and the requirement for many of the magnetic components, making the Invertor Welders considerably lighter in weight and smaller in size and thus easier to carry around. Plus with a higher frequency of the output current, an inverter welder produces a smoother arc when welding and at the same time is more energy efficient since it consumes less electricity.
Perfectly suited for Inverter Welding Applications are the new ON Semiconductor NGTB25N120S 1200V/25A IGBTs which feature a robust and cost effective Trench construction, and provide superior performance in demanding switching applications, offering both low on state voltage and minimal switching loss. These IGBTs make it possible to build a switched-mode power supply capable of coping with the high loads of arc.

If the origins and practice of welding are so old that it ‘came out of the ark’, then it’s great to know that ON Semiconductor’s innovative IGBT technology can now help create the perfect arc!
