1. A distributed hybrid propulsion system, comprising:
an engine assembly comprising an engine, which is non-propulsive;
a first active rectifier;
an energy storage element;
a converter;
a motor-generator;
a second active rectifier;
a common bus to which the engine assembly is connected via the first active rectifier, to which the energy storage element is connected via the converter and to which, the motor-generator is connected via the second active rectifier; and
bi-directional power flow control elements, which are controllable to manage bi-directional power flow between the engine assembly, the energy storage element and the motor-generator,
the bi-directional power flow elements comprising:
a first switch between the first active rectifier and each of the converter and the second active rectifier;
a second switch between the converter and loads; and
a third switch between the second active rectifier and each of the converter and the first active rectifier.
