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.
