Abstract
This paper proposes an aggregated model of multiple power factor correction (PFC) converters used for data centers. The parameter scaling and aggregation rules for paralleled single-phase PFC converters are derived first, where different powers and line distances of PFC converters are considered. Then, a reduced-order impedance model of three-phase data center power system is developed based on the aggregated model, which allows a more efficient analysis of system interactions of PFC converters. The accuracy of theoretical analyses is finally validated by simulations and experimental tests.
