A Gen-3 10-kV SiC MOSFET-Based Medium-Voltage Three-Phase Dual Active Bridge Converter Enabling a Mobile Utility Support Equipment Solid State Transformer

Review of Dual-Active-Bridge Converters With Topological Modifications

“…By the way, it is pointed out in [182] that three two-winding transformers connected in a three-phase configuration provide the same functionality as a three-phase multi-winding transformer. Two-winding transformers can be constructed more easily with commercially available magnetic cores, and they are used in [181]- [183]. In addition to the push-pull structure and multi-connection in the DAB3 converter, there are other cases that used multiwinding transformers.…”

A Review of Power Converters for Ships Electrification

“…This topology suffers from high input Total Harmonic Distortion (THD) and electromagnetic interference issues. Sciberras et al [18], Zhu et al [24], and Anurag et al [25] proposed a front-end active bridge rectifier to replace the diode bridge rectifier and achieve low THD and high power factor. Six-pulse, 12-pulse, 18-pulse, or 24pulse rectifiers are alternatives to reduce the harmonics further [3], [18], [26], [28].…”

“…Frequency converters: (a) Three-phase diode bridge rectifier. (b) Three-phase active bridge rectifier [18], [24], [25]. (c) Twelve pulse rectifier [3], [18], [26].…”

Test Platform for Comparative Evaluation of 690 V – 4160 V Power Electronic Converters

“…A few researchers have also built PECs entirely with SiC devices; in [18] a 855 kVA 4-stage SiC based MV PEC system was built back in 2011 with a total efficiency of 97% equating to a single converter efficiency of above 99.2%. In [27] a 100 kW 4-stage PEC system was built utilizing 10 kV SiC MOSFETs on the MV side, this converter was tested up to 30 kW of active power with no efficiency specified. An efficiency of 99.1% was reached in a 25 kW test for a single phase 2L converter switching at 48 kHz in [28] and in [29] a three phase 100 kVA multi-level PEC with 15 kV SiC MOSFETs was built, reaching DC voltage levels of 20 kV and having an efficiency over 97%, but due to power supply limitations only 14 kW was circulated per phase.…”
