Patent ID: 7848122

Claim:
A terminator for reducing electrical transients on a power cable having three conductors to provide three-phase power to an AC motor from a solid-state motor drive, the terminator comprising: three differential-mode damping elements each having a series connected resistive and capacitive component, the differential-mode damping elements connected to each of the three conductors to provide equal impedances from each conductor to the other conductors; at least one common-mode damping element having a series connected resistive and capacitive component, the common-mode damping element providing a path from each conductor to ground; wherein the differential-mode damping elements provide impedance between each of the conductors substantially equal to a differential-mode characteristic impedance of the power cable and wherein the common-mode damping element provides an impedance between each of the conductors and ground substantially equal to a common-mode characteristic impedance of the power cable.
