FROM AC TO DC

摘要

Abb has launched a new DC (direct current) electrical system for marine applications.It is designed for ships with low-voltage onboard power systems, such as offshore support vessels, tug boats, ferries and yachts.In traditional electrical propulsion vessels, multiple DC connections are made from the AC circuit to thrusters and propulsion drives, which account for more than 80% of electrical power consumption. ABB's onboard DC system represents a step forward in optimized propulsion by connecting all DC links and distributing the power through one main DC circuit.
