High-voltage direct-current (HVDC) based power distribution networks have become an attractive alternative to classical ac distribution networks in more electric aircrafts (MEAs). This paper proposes a power flow management system for an isolated multiport power converter (MPC), which includes a highfrequency transformer, that controls the power flow between three HVDC electric networks in MEAs. The operation of the MPC system and the control stability analysis are presented. The proposed power flow management is tested under normal operation mode and different fault conditions of the power generators. The experimental results demonstrate that the isolatedMPCreduces the effect of a power generator failure to the other networks, thus enhancing the fault tolerance of the entire power distribution network of the aircraft.
