Desarrollo e implementacion de un convertidor cc-cc bidireccional de doble puente activo.

摘要

In this work development of a modulation scheme, a unified starting sequence and construction of a programmable isolated bidirectional dual active full-bridge dc-dc converter to interconnect a 48 V dc bus and a 300V dc bus within a universal testbed are presented. Flexibility and ease of reconfiguration are provided by a digital signal processor which also produces control sequences that guarantee proper operation both in steady state and at start-up. Experimental results from a scaled prototype validate predictions by simulations with developed modulations and sequences.
