| Abstract |
In industrial low and medium voltage mains, passive filters and PFC capacitors have traditionally been
used to improve the supply quality. However, they cannot be rated only for the loads being compensated.
They are affected by harmonic currents from other non-linear loads or by harmonics from the power
system.
Compared with passive element compensators, the Mains Active Restoring System (MARS) can be used
to improve the supply quality without worrying about all the problems associated with applying passive
elements. |
