DC-link film capacitors can effectively suppress voltage fluctuations and filter high-frequency noise in the DC support filter circuit of wind power generation, solar power generation and other industrial frequency converters, thereby improving the efficiency of power conversion.

Features

DC-link film capacitors can be used in DC filter circuits to replace traditional electrolytic capacitors and provide more stable and efficient filtering effects.
It has a small equivalent series resistance, can withstand large ripple current, reduce energy loss and improve system efficiency.
The DC-link capacitor has low self-inductance, suitable for high-frequency applications, ensuring fast response and stable operation.
It has self-healing properties, which can repair minor damage caused by overvoltage or other abnormal conditions to a certain extent and extend service life.
The aluminum shell design and resin potting process of the capacitor provide good mechanical strength and resistance to environmental interference.

Applications

Tips: What is a DC-link capacitor?

DC-link capacitors are capacitors used in direct current (DC) circuits, mainly used in DC support filter circuits in power electronic equipment. Its main function is to stabilize the DC voltage in the circuit, reduce voltage fluctuations and high-frequency noise, and smooth the current waveform to ensure the stability and efficiency of the system. DC-link capacitors play an important role in renewable energy systems (such as wind and solar power generation) as well as industrial inverters, power converters and other applications.

Builder in Product TAB

NEW! Since Journal 3.2, the much improved T.A.B (Tabs Accordion Blocks) system supports the page builder inside the tab content. Unlimited Blocks, Tabs or Accordions with any HTML content or the builder interface (supporting custom rows/columns/modules) can be assigned to any individual product or to certain groups of products, like entire categories, brands, products with specific options, attributes, price range, etc. You can indicate any criteria via the advanced product assignment mechanism and only those products matching your criteria will display the modules. Also, any module can be selectively activated per device (desktop/tablet/phone), customer login status and other criteria. Imagine the possibilities.
