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).
