SISO Filters
1.1
SISO (Sine In – Sine Out) LCL and LC filters combine both differential (DM) and common-mode (CM) filtering. SISO filters enable
installations without a transformer, for example, for marine and energy storage applications.
Two different types of the SISO filter are available:
SISO-LCL-0525-5-0-AFTP
l
SISO-LC-0525-5-0-AFTP
