This paper presents a current-stress-optimized (CSO) triple phase shift (TPS) modulation strategy for dual active bridge (DAB). The current stress and transmission power of each effective switching mode is expressed by three control variables. The global current stress minimization of TPS is obtained by using Karush-Kuhn-Tucker (KKT) condition. Simulation results verify the effectiveness of the TPS modulation strategy.

摘要

This paper presents a current-stress-optimized (CSO) triple phase shift (TPS) modulation strategy for dual active bridge (DAB). The current stress and transmission power of each effective switching mode is expressed by three control variables. The global current stress minimization of TPS is obtained by using Karush-Kuhn-Tucker (KKT) condition. Simulation results verify the effectiveness of the TPS modulation strategy.
