With the rapid development of science and technology today, large-scale integrated circuit technology, especially semiconductor-related technology, can be regarded as the cornerstone of scientific and technological progress. However, the ever-changing international environment in recent years has caused many industries to encounter a "cold winter" in chip supply. Under the guidance and strong support of national policies, the semiconductor industry has ushered in vigorous development, and new semiconductor factories have sprung up like mushrooms after rain. In the design and construction process of semiconductor electronic factories, harmonic suppression is a top priority, and many factors such as the harmonic level of the power grid and the harmonic tolerance of precision equipment need to be comprehensively considered. So, where do harmonics come from? What impact will it bring?
Sources and hazards of harmonics
Harmonics are like "troublemakers" in the power grid
-The use of a large number of nonlinear loads will generate harmonics, affecting the quality of power;
-The harmonics generated by the inverter during operation will have an adverse effect on the power grid and equipment;
-Harmonics from the power grid will increase the loss and temperature rise of electrical equipment, causing certain damage to the equipment.
Solution Introduction
In industrial production scenarios with extremely high harmonic requirements, such as semiconductor electronic plants, the harmonic suppression standards are extremely strict. Taking electronic clean plants as an example, according to the IEC or IEEE519 standards, THDi needs to be controlled at around 5-16%, while semiconductor electronic plants usually have more stringent requirements, limiting it to less than 10%.
Inverters, passive filters and output reactors, as core components of the electric control system, their coordinated operation plays a vital role in improving system stability, extending equipment life and optimizing power quality.
Sine Electric focuses on the needs of the semiconductor electronics industry and launches high-reliability solutions to fully guarantee the stable operation of the power system of semiconductor electronic plants and lay a solid foundation for the development of the industry.
Solution Advantages
1- Harmonic suppression, power quality improvement
The sine electrical solution can accurately filter harmonics, "clean up" the power grid environment, and improve the power quality and power factor of the power grid.
2- Extended equipment life
By effectively suppressing harmonics, it can be protected from harmonic damage, extend the service life of equipment, and reduce maintenance costs.
3- Stable system, ensure production and processing
Reduce the interference of harmonics on high-end precision instruments and improve product processing accuracy.
4- Electromagnetic compatibility, environmental protection and energy saving win-win
The inverter has built-in C3 filter and DC reactor, plus passive filter and output reactor, which suppress harmonic interference, ensure harmonious coexistence with other electronic equipment, and achieve a win-win situation for economy and environment.
Core components
Semiconductor electronic factory projects have long been dominated by imported brands. Sine Electric has accurately anchored the pain points of the industry, actively responded to market demand, and insisted on independent innovation to successfully break through.
So far, Sine Electric has successfully applied and implemented the "inverter + passive filter + output reactor" solution in multiple semiconductor electronic factory projects, providing a solid guarantee for the stable operation of the project.
With the accelerated advancement of industrial automation, power electronics technology is also continuing to innovate and break through. Sine Electric's cutting-edge solution will move towards a more sophisticated and intelligent direction, injecting strong momentum into building green, efficient and stable semiconductor electronic factories, and leading the industry into a new stage of development.
