condensed Three-phase rectifier
input filter DCS - 4 pieces.
It features voltage source inverter (VSI) topology with a three-phase rectifier
, DC link and multi-level output converter using Neutral Point Clamped (NPC) technology with 3/5 voltage level for output voltages from 2.
A three-phase rectifier
is characterized by a very inductive DC side configuration relative to the AC system side.
INDRA and CEI-UPM, the consortium that is presenting this proposal, has a wide experience in the area of high performance TRUs for the new aircraft requirementsThe basic architecture that allows for these high performance TRUs has three stages: 1) EMI filter to meet the EMI standards, 2) Active Three-Phase rectifier
to control the demanded sinusoidal current (THD and PFC) as well as control the output dc voltage (VBUS DC) and 3) isolated dc/dc converter that provides galvanic isolation, adapts the voltage and power to the specifications (28V) and it can be in charged of some control capabilities (battery charge mode, voltage source mode, current source mode, some protections).
Unique impact of three-phase rectifier
on dynamic studies compared with conventional models is evaluated by using its validated model in transient stability analysis of IEEE 9-bus test system performed by PSCAD/EMTDC.
