Case 2: Aluminum Electrolysis High Voltage Wide Temperature -40 ℃ ~ 125 ℃, Application of High Voltage Series Products in Industrial Power Supply

The global aluminum electrolytic capacitor supply market is maturing, mainly concentrated inJapan, Mainland China,Taiwanregions and South Korea. From the perspective of the overall competition pattern of the industry in recent years, the production of electrolytic capacitors in Japan has gradually shrunk and reduced production, replaced by South Korea companies, Taiwanese companies, and Chinese mainland companies. Before 1978, aluminum electrolytic capacitor was regarded as a product in mainland China at that time.high-tech productsAfter more than 30 years of development, aluminum electrolytic capacitors are no longer high-tech products for domestic aluminum electrolytic capacitor manufacturers. From a technical point of view, the capacitors produced by some well-known domestic brands can completely replace foreign ones.Capacitance.

 

Industrial aluminum electrolytic capacitors are mainly used in industrial and communication power supplies, professionalFrequency converterCNC and servo systems, windPower generationAnd automotive and other industrial fields, special aluminum electrolytic capacitors are mainly used in military, aerospace and other special fields, these applications use aluminum electrolytic capacitors, not the past regular.Rated working voltage 6.3-450V, working temperature -25~105℃, but the working voltage is higher.500V,550V,630V(Series-parallel mechanical mode or single mode), working wide temperature -40~125The product is extended.

 

  Therefore, research and development projects are needed to solve the damage to aluminum electrolytic capacitors caused by the changeable outdoor climate. Aluminum electrolytic capacitors have high temperature resistance, humidity resistance, and capacitors need to be moisture-proof and must work at 85°C and 85% relative humidity;

At the same time to overcome the conduction interference (EMI) and other safety regulations AEC-Q200 higher requirements and other superimposed factors of new products, new areas. In particular, it points out a series of problems such as various interference waveforms or spectra (as shown below) for aluminum electrolytic capacitors.Recent R & D projects have introduced new products that respond to market needs, suchOperating Wide Temperature -40~105C, and-25~125℃ voltage 500V,550V,600V,630V and other large leads and horns, bolt product extension......
