According to media reports, Taiwan's Hsinchu Science Park had a large-scale power jump accident at 15:18 p.m. on March 1, 2022, which affected the production of manufacturers such as internal power, TSMC, world advanced, and Youda Optoelectronics in Hsinchu Science Park. The sudden power failure of the accident is only 0.1 seconds, and the voltage drop range of each plant on that day is between 79% and 95%, which has an impact on the relevant machines equal to "power failure". In fact, Taiwan's semiconductor manufacturers are not alone in the occurrence of power tripping accidents. In April last year, about 30000 wafers of TSMC were affected due to the tripping of ultra-high voltage transformer circuit in TSMC's Nanke plant, and the estimated loss was about NT $1billion. It can be seen that the semiconductor industry is extremely sensitive to voltage sag due to the continuity of production and automatic control. Every voltage sag will bring huge economic losses to enterprises, and even major safety accidents.

Avic-tec AVR series dynamic voltage restorer system perfectly solves the voltage sag of 0.1 seconds

Voltage sag has become the most prominent problem affecting the stable operation of power load. AVIC Tec AVR series dynamic voltage restorer is "a good medicine", which perfectly solves the power quality problems such as voltage sag, voltage surge and short-term interruption for users.

At present, the single machine capacity of avic-tec AVR series dynamic voltage restorer has reached 3150kva, which is the largest single machine capacity in China. It has been put into operation in the semiconductor industry to ensure that the user's production line load is free from voltage sag. AVR series dynamic voltage restorers have attracted much attention from semiconductor manufacturing, petrochemical, chemical, automotive manufacturing, precision processing, pharmaceutical, paper making, medical and health care, scientific research institutions, tobacco, ceramics, metallurgy, steel, printing, glass, textile and other industries.
