Abstract: An electrical system and method of operating the same is provided. The electrical system includes a passive filter, an active power converter, a first AC connecting bus extending between the active power converter and the passive filter, a second AC connecting bus extending between the passive filter and an AC network, a DC connecting bus extending between the active power converter and a DC network, and a monitoring arrangement. The method includes operating in a first mode and subsequently operating in a second mode. The first mode includes determining a plurality of parameters of an operating AC voltage of the AC network based on a monitored AC voltage on the first AC connecting bus. The second mode includes controlling the active power converter to convert a DC voltage received from the DC network into an AC voltage for supply to the AC network via the passive filter.

Abstract: The present disclosure relates to an apparatus for supplying electrical power to a transport refrigeration unit. The apparatus comprises: a power converter including a rectifier, a first inverter and a DC link; a power distribution unit electrically coupled to the DC link; and a second inverter with an input for electrically connecting to an electrical generator and an output for electrically connecting to the power distribution unit or the DC link. The DC link is electrically connected to an output of the rectifier and an input of the first inverter. An input of the rectifier is electrically connectable to a power source external to the apparatus. An output of the first inverter is electrically couplable to the transport refrigeration unit. The second inverter is configured to convert an alternating current voltage supplied at the input into a direct current voltage for supply at the output.
