Patent ID: 7092229

Claim:
A device for reducing currents in an electrical system which supplies power to a nonlinear load from an AC source, comprising: a first passive electrical component connected in series with the nonlinear load; a second passive electrical component connected in parallel to said first passive electrical component; a third passive electrical component connected in parallel to said first and said second passive electrical components; said first, second and third passive electrical components are tuned to a third harmonic frequency of the AC source so as to substantially alter current drawn by the nonlinear load; a housing member for said first, second and third passive electrical components; means for connecting the nonlinear load to said parallel connection of said first, second and third passive electrical components; said connecting means includes an equipment rack panel member connected to said housing so as to mount said housing in an equipment rack storing the nonlinear load; and said equipment rack panel member is substantially perforated so as to allow airflow to pass therethrough.
