Hong Kong Applied Science and Technology Research Institute Company Limited (ASTRI) has developed a semiconductor-based digital ultra-fast DC circuit breaker for protecting the power source, load, and cables in LVDC grid from damage in abnormal electric conditions.
To address the short circuit failure is DC voltage that cannot be effectively protected by DC mechanical circuit breaker, ASTRI has developed a semiconductor-based digital ultra-fast DC circuit breaker for LVDC applications to protect the power source, load and cables from damage in abnormal electric conditions, such as short circuit and overload, in a “microsecond range” protection speed.
The Hong Kong Applied Science and Technology Research Institute (ASTRI) was founded by the Government of the Hong Kong Special Administrative Region in 2000 with the mission of enhancing Hong Kong's competitiveness through applied research. ASTRI’s core R&D competence in various areas is grouped under five Technology Divisions: AI and Big Data Analytics; Communications; Cybersecurity, Cryptography and Trusted Technologies; Integrated Circuits and Systems; and IoT and Sensors. It is applied across five core areas which are Smart City, Financial Technologies, Intelligent Manufacturing, Digital Health, and Application Specific Integrated Circuits.
