Optimized Control of Dual-active-bridge DC/DC Converter Based Power Electronic Transformer With Dual-phase-shift Control

摘要

(outer phase shift ratio), an optimal DPS control scheme is proposed for DPS control by employing an evaluation coefficient to investigate the influence of the disturbances of control variables on the transmission power and backflow power. It can minimize the backflow power and reduce the power losses. Simulation results are provided to validate the correctness of theoretical analysis and the effectiveness of the proposed scheme.
