Congratulations to Global Power Technology for "DNV and USCG certification"

Recently, GPT successfully passed the certification of the United States Coast Guard with the international ship standard, becoming the first silicon carbide power electronics company in China to obtain DNV and USCG certification.

In the current difficult time to fight the epidemic, new certification is undoubtedly the first good news for our company after the 2020 Spring Festival.

Global Power Technology DNV and USCG certification

The emergence of ship power supply is a special ship power supply that meets the requirements of offshore platforms, ships and related special environmental power protection requirements. Due to the particularity of maritime fields such as offshore platforms and ships, the navigation equipment, emergency lighting systems, lifesaving systems, IT equipment, communication systems and other marine equipment used by them have higher requirements for the stability and reliability of power supply systems. As the space inside the offshore platform or cabin is relatively limited, the design of related electrical equipment needs to take into account the tolerance of high ambient temperature, high ambient humidity, high salt spray environment, and resistance to vibration, tilt, and swing conditions. Therefore, during the design process, the designer of electrical equipment must strictly select the electrical components to ensure that they can ensure the requirements of high reliability and long life under these harsh conditions. The internal power semiconductor components, as the core components of electrical equipment, must strictly comply with international standards to ensure their reliability and working life.

Compared with other high-power ground power supplies, high-temperature, high-pressure, high-reliability SiC devices are also more suitable, and their application prospects are broader.
