Abstract This paper investigates auxiliary power supply system of the input series modular power electronic converter (ISOP/ISOS). The input series output independent (ISOI) structure is utilized to improve the modularity of the auxiliary power supply system. In order to ensure input voltage sharing (IVS) between each modules, a novel master-slave input voltage sharing control strategy is proposed. For this control strategy, there is no connections between each controllers, and it has the advantages of simple design process and high degree of modularity. The stability of this control strategy is analyzed, the design process of the controllers is given and the relationship of output voltages between each modules is discussed. Finally the effectiveness of the system architecture and control strategy is verified by a prototype of ISOI auxiliary power supply system.

Key words： Modular auxiliary power supply input series output independent master-slave input voltage sharing control strategy input voltage sharing
