Abstract
This paper proposes a reduced 3rd harmonic current of server power supply units which effects of heating neutral cables and transformer. The data centers require the operation of many parallel-connected switch mode power supply on the same bus and transformer. Such a system significantly increases the high neutral current and power quality problems on the distribution network. Finally, using the Hybrid Power Filter System(HPFs) to solve this problem, the results can reduce distortion in current. The HPF is the combination of Active Power Filter (APF) and Passive Power Filter (PPF) which mostly use for reducing 3rd, 5th currents and power quality improvements of the system.
