9.1.5Bypass Current Sharing Inductors

Applicable in paralleled UPS configurations to ensure that the (passive) static bypass switches, when activated, share the load current. The inductors provide droop type current compensation for the oth- erwise inherent current dispersion due to SCR and cable impedance differences.

Three bypass current sharing inductors are assembled within each UPS cabinet without requirement of additional footprint. The resulting degree of unbalance is typically less than 20% of the rated sys- tem current depending on the external cable configuration. Cable lengths from the Bypass supply to each UPS module and from the UPS module output to the paralleling point should be kept as identi- cal as possible.
