Electrical power distribution systems and methods of operating electrical power distribution systems are provided. One electrical power distribution system comprises: an electrical power storage unit; a transformer; a first bidirectional converter circuit connected between the electrical power storage unit and a first winding of the transformer; a first DC bus; a second DC bus; a second bidirectional converter circuit connected between the first DC bus and a second winding of the transformer; a third bidirectional converter circuit connected between the second DC bus and a third winding of the transformer; and a controller connected for control of the first, second and third converter circuits to distribute electrical power between the electrical power storage unit, the first DC bus and the second DC bus.

Electrical power distribution

An operating condition monitor () for monitoring an operating condition of a transistor-based power converter (), comprising: a sensing apparatus () configured to measure a turn-off transient energy of the power converter (), a processor () in communication with the sensing apparatus () to receive the measurement of the turn-off transient energy, the processor being configured to: compare the measurement of the turn-off transient energy to a threshold; and issue an event signal based on the comparison to the threshold meeting a comparison criterion. A method (') of monitoring an operating state of a transistor-based power converter is also disclosed.
