Smoothing Reactor: A Critical Component in DC Power Systems
A smoothing reactor is an essential electronic device used in DC circuits after rectification. It plays a vital role in filtering and stabilizing direct current by reducing ripple currents, suppressing harmonics, and limiting fault currents. These reactors are widely employed in high-voltage direct current (HVDC) converter stations and thyristor-based electric drives with DC power supplies. In HVDC transmission systems, smoothing reactors are indispensable for ensuring system stability, efficiency, and reliability.
