Popis: | This paper first analyzes the fault characteristics of a dual active bridge topology with switched capacitors (SCDAB) when a port short-circuit fault occurs on the input side. At the same time, an improved topology (FBDAB) is proposed, which can use its unique freewheeling charging stage to recharge the capacitor voltage to supplement the power loss to a certain extent, which is beneficial to the rapid recovery of the DC transformer after failure and speeds up the restart process. Finally, in the simulation software MATLAB / Simulink, the feasibility and effectiveness of the proposed topology are verified. |
