PROJECT TITLE:

Variable-Frequency Phase Shift Modulation of a Dual Active Bridge Converter - 2015

ABSTRACT:

In this paper, a variable-frequency modulation method for a twin active bridge converter is introduced. The proposed methodology ensures zero-voltage switching over a good power range with a minimal circulating current. Unlike previously presented modulation schemes, this modulation methodology can also be used for 0.5-bridge variants of a ancient dual active bridge converter. The modulation technique is given during a closed kind, which makes it simple to use in follow. Further, the phase drift phenomenon is mentioned, and a simple part drift compensation scheme is presented. Finally, a detailed analysis of the proposed modulation technique is provided and its feasibility is verified by measurements.
