Abstract
This work focuses on the design of high-efficient DC-DC converters based on WBG power devices. The first objective is the development of an isolated bidirectional converter for the distribution network of future electrical aircrafts. A SiC-based Dual Active Bridge converter is designed and fabricated. Control strategies for individual and parallel operations are investigated and implemented into a FPGA platform. Experimental results on 1.2kW 270V/28V prototype are presented to confirm the proper behavior of the proposed solution. The second project belongs to the field of photovoltaic systems and aims to develop a three-port converter with multiple power elements interfacing capability. A GaN-based Triple Active Bridge has been designed, regarding both the controller and the hardware realization.I documenti in UNITESI sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
