Inductive reactors

EGS

SVX

Mitigates higher-order harmonics by providing high input impedance that limits high-frequency currents. 33-38%
Low-cost, simple application

Low effectiveness

Voltage drop concerns

12-Pulse converters
HCX
Two parallel 6-pulse converters fed by parallel isolation transformer paths, phase shifted 30°, which mitigates 5th and 7th order harmonics. Input impedance mitigates higher-order harmonics as well. 12-18%

Simple to apply

Extremely robust

Not as effective as other methods

Relative high cost compared to passive filter

Passive filters

EGF

CFX

Provides high input impedance for higher-order harmonics and a shunt-tuned reactor and capacitor to mitigate 5th and 7th harmonics. 6-8%

Simple retrofit

Low cost for performance

Insensitive to voltage balance

Challenges with generator design

Power factor issues

Less robust than 18-pulse

18-Pulse converters
CPX
Three parallel 6-pulse converters fed by a single-phase shifting autotransformer, phase shifted 20° to cancel all harmonics below the 17th. Input impedance mitigates higher-order harmonics as well. 3-6%

Simple to apply

Extremely robust

Higher cost on small hp
Active Front End drives
RGX
IGBT-based front end pulls relatively linear power from the line and uses a L-C-L filter to mitigate the IGBT switching noise. 3-5%

Slightly higher efficiency

Immune to voltage imbalance

Regeneration capability

High cost, not as robust as 18-pulse
