摘要：
The development of electric energy routers contributes to more and more concerns about the topologies with high-frequency square-wave AC link. Compared with the traditional topologies with a DC bus, the modular multi-active bridge topology with an AC bus is able to flexibly achieve the expansion of the ports with various voltages and power levels through its modular designing. In this paper, the control strategies of the DC port of this topology is studied, including the voltage balancer and the modular multi-active bridge. Based on the modeling and analyzing of the circuit, the control strategies for the port under both constant power mode and constant voltage mode are given, and the mode transfer strategy is deduced. Aiming at the port with bipolar DC voltage, the corresponding voltage balancer modeling and control strategy are given. Finally, the strategy is verified by simulation and experimental prototypes. © 2020, Power System Technology Press. All right reserved.
