The technology optimizes the switching characteristics of power semiconductor devices. This allows stable phase output even under high-frequency operation. As a result, it’s ideal for fields like wind power and petrochemicals, where phase control demands are strict.
The module features a modular internal design. It integrates the phase control unit, signal interface, and heat dissipation system into one unit. This enables quick replacement and maintenance. Notably, its heat dissipation system uses a bionic design. It optimizes airflow paths through fin structures. Even at 45°C ambient temperature, the module’s temperature rise stays within 30K—ensuring long-term reliability.
II. Industry Applications: From Power Systems to Special Environments
Power System Protection and Control
In a 500kV substation renovation by State Grid, the S-073N module paired with the ACS6000 series high-voltage frequency converter. It monitored grid phase fluctuations in real time to achieve dynamic reactive power compensation. This cut the grid harmonic distortion rate from 8.2% to 2.1%, meeting national Class A standards. The case is now in ABB’s global Smart Grid Solutions White Paper.
