Why can DC-LINK DC support capacitors replace ox horn electrolytic capacitors and bolt electrolytic capacitors
With the continuous development of power electronics technology, various power electronic devices are widely used in various power supply systems and power systems. Therefore, the safety and reliability requirements for power electronic devices have become increasingly high. Among these devices, capacitors are an indispensable part, their function is to store electrical energy and provide transient power. However, traditional electrolytic capacitors have some drawbacks, such as short lifespan, susceptibility to bursting, and difficulty in solving problems without protection. It can affect the performance and reliability of equipment, and also pose potential safety hazards to the entire power supply system. A new type of DC support capacitor, DC Link capacitor, has emerged to address these issues. DC Link capacitor is a type of solid-state capacitor with high reliability and long lifespan, which can replace traditional electrolytic capacitors and bolt capacitors. This article explains how to fully charge the battery. Explore the advantages and applicability of DC Link capacitors in the following aspects.
1、 High reliability
The reliability of electrolytic capacitors has always been one of the bottlenecks in power system design. Traditional electrolytic capacitors have a shorter lifespan and are susceptible to environmental factors such as temperature, humidity, and voltage, making them prone to malfunctions and failures during use. As a solid-state capacitor, DC Link capacitors have higher reliability and other characteristics. Using solid polymer electrolytes, there is no liquid electrolyte, so there will be no leakage, rupture, or other related issues,. DC Link capacitors also have characteristics such as low ESR (equivalent series resistance) and high self-healing, which can ensure their stable performance during long-term use.
2、 Long lifespan
The lifespan of electrolytic capacitors is also a crucial factor in the lifespan of capacitors in electrical measurement systems., It generally ranges from 5000 to 20000 hours, while the lifespan of DC Link capacitors is much longer, reaching 50000 to 100000 hours or even longer. Long lifespan can greatly reduce maintenance costs and downtime of equipment, and improve its reliability and stability.
3、 Good safety performance
Electrolytic capacitors are prone to failure during use due to various factors such as temperature, humidity, pressure, etc. These factors may lead to safety issues such as capacitor rupture or explosion. The DC Link capacitor uses a solid polymer electrolyte, which does not have a liquid electrolyte, so there will be no problems such as leakage or explosion. In addition, DC Link capacitors also have characteristics such as low voltage breakdown and high insulation resistance, which can ensure their good performance during use good
4、 The safety suitability should be able to withstand harsh environmental conditions. Electrolytic capacitors are susceptible to various environmental factors such as temperature, humidity, mechanical stress, etc. during use, which may lead to capacitor failure or damage. DC Link capacitors have good stability and reliability, and can adapt to various harsh environmental conditions, such as high temperature, low temperature, humidity, vibration, etc. Therefore, in the design of power systems, DC Link capacitors can better adapt to various environmental conditions, ensuring the reliability and stability of equipment.
5、 High energy density
Although electrolytic capacitors have a high capacitance, due to their large volume, their density L is lower than that of d. K capacitors use new materials and processes such as solid-state polymer electrolytes and metallized electrodes, which have a smaller volume and higher energy density. This means that under the same capacitance, DC Link capacitors have a smaller volume, lighter weight, and are more suitable for high-density power system design.
6、 Summary
DC Link DC support capacitor, as a new type of solid-state capacitor, has high reliability, long lifespan, good safety performance, and is suitable for harsh electrical environment, as well as a dense electrical source with high device capacity reserve, and other system characteristics in point design and optimization,. DC Link capacitors can replace traditional electrolytic capacitors and bolt electrolytic capacitors, improve equipment performance and reliability, reduce maintenance costs and downtime, ensure equipment safety performance and adapt to various environmental conditions. Therefore, the application prospects of DC Link DC support capacitors are very broad.
