DC Link Capacitor Function

A DC Link capacitor is an important component in many power electronic systems. It is positioned in the DC link section of a power conversion circuit and is used for energy storage and DC-link voltage management.

The product is designed for applications where the DC-link circuit requires a capacitor with defined voltage, capacitance, temperature and service-life characteristics.

The available voltage range of 600–2000V DC and capacitance range of 150–1500μF provides configuration flexibility for different power conversion system designs.

Photovoltaic Applications

Photovoltaic power systems use power electronic equipment to convert and manage generated electrical energy. The DC Link capacitor can be incorporated into suitable photovoltaic power conversion equipment as part of the DC-link circuit.

Its wide voltage and capacitance ranges allow system designers to select an appropriate specification according to the electrical design.

Wind Power Applications

Wind power conversion systems require power electronic components capable of operating within the specified electrical and environmental conditions. The DC Link capacitor can be used in suitable wind power converter systems where DC-link energy storage and voltage stabilization are required.

The -45°C to +70°C operating temperature range provides a broad specified temperature window for applicable equipment designs.

SVG Applications

The capacitor is also suitable for SVG (Static Var Generator) equipment. In an SVG system, the DC-link section is an important part of the power conversion structure, and the capacitor can be selected according to the required DC voltage and capacitance.

Before application, system designers should confirm electrical compatibility and operating conditions.

Frequency Converter Applications

The product is designed for frequency converter applications where a DC Link capacitor is required. The available voltage range of 600–2000V DC and capacitance range of 150–1500μF can accommodate different frequency conversion system requirements.

The appropriate specification should be selected based on the converter's electrical design, DC-link voltage, capacitance requirement, operating temperature and available installation space.

Housing and Construction

The capacitor uses an aluminum housing with a plastic cover. This construction provides a defined external enclosure while maintaining the required mounting and grounding interfaces.

The product uses dry-type resin potting. The potting structure is designed to protect the internal capacitor assembly and provide a stable component structure for integration into power electronic equipment.

Installation Options

Two installation approaches are specified:

Bottom Grounding Bolt Installation

The capacitor can be fixed using grounding bolts positioned at the bottom of the aluminum housing. This method combines component fixation with the designated grounding interface.

Mounting Foot Installation

The capacitor can also be installed using mounting feet. This option can be selected when the equipment structure requires a foot-mounted configuration.

The actual installation method should be determined according to the equipment design and available mounting structure.

Product Diameter Options

Four product diameter options are available:

• 86 mm

• 96 mm

• 116 mm

• 136 mm

The appropriate diameter should be selected according to the required capacitance, voltage specification, internal equipment space and mechanical installation requirements.

Operating Temperature

The specified operating temperature range is:

-45°C to +70°C

When selecting and installing the capacitor, the actual equipment environment should remain within the applicable operating conditions. Thermal management of the complete power electronic system should also be considered during equipment design.

Expected Service Life

The expected lifespan of the product is 100,000 hours. Actual service life can depend on operating voltage, temperature, ripple current, load conditions, cooling conditions and other system parameters.

For long-term operation, system designers should select the capacitor according to the actual electrical and environmental requirements of the application.
