Dead-time Compensation Method for Dual Active Bridge Converter with Three-level Operation

Abstract

This paper proposes a compensation method for the non-liner error of the transmission power caused by dead-time in a dual active bridge (DAB) converter with three-level operation including zero-voltage phase. The non-liner error of the transmission-power is compensated by using three-level operation. From the experimental results, the error of the transmission power caused by dead-time is reduced by 78.9%.
