Reactive T-topology four-terminal-network compensator for multiharmonic current

This paper presents a new method for passive current compensation of a real multiharmonic power source with the use of a four-terminal network. In contrast to a two-terminal compensator, a four-terminal-network compensator can fully separate the supply circuit from the load. This ensures optimal operating conditions for the source while keeping the voltage and load current unchanged. The source’s optimal working conditions mean that the source current reaches its minimal RMS value (becoming the so-called “active current”) while it transmits the desired active power to the load.
