摘要/Abstract

摘要：

双有源桥变换器具有良好的软开关、电气隔离、功率调节能力,被广泛应用于直流输电、储能、列车牵引等领域。双有源桥变换器的调制算法与效率密切相关,原副边电流大小、器件开关时刻等重要因素均由调制算法决定,并直接影响器件开关时刻的损耗。提出一种基于综合损耗最优的双有源桥式变换器调制方法,该方法能够依据双有源桥变换器的不同工作模态情况进行损耗建模,计算器件的导通损耗与开关损耗,并综合总损耗确定最优的调制策略。最后,通过PLECS仿真验证了该方法的可行性和有效性。

Abstract:

Dual active bridge converter is widely used in energy storage, traction, DC power transmission due to its good performance in soft-switching, electric isolation and power control ability. Modulation strategy, which decides the current in primary /secondary side and the switching time of the switches, is important for dual active bridge and has great influence on efficiency. The power loss of switches can be calculated under certain modulation strategy. In this paper, an optimum efficiency orientated modulation strategy is proposed. The conduct loss and switching loss are both considered based on the different working mode of dual active converter, and the modulation with lowest total losses and best efficiency can be chosen. The PLECS simulation results show the correctness and effectiveness of proposed strategy.

Key words: Dual active bridge, modulation strategy, efficiency improve, lowest total losses
