三电平双有源桥变换器的瞬态直流偏置抑制

Dual-active-bridge (DAB) dc–dc converter usually adopts phase-shifting control to control the power transmission of DAB converter. As the theoretical premise in the steady state analysis cannot be satisfied during the adjustment process of phase shift value updating, it leads to the generation of transient dc bias. To address the transient dc bias problem of the three-level DAB converter, a transi...
