Abstract
A transport refrigeration unit (TRU) direct current (DC) architecture includes a communications bus (41), a DC power bus (42), first and second voltage control units (VCUs 43,44) respectively comprising a DC/DC converter (430) coupled to the DC power bus and a local controller (431,441) coupled to the communications bus and to the DC/DC converter, an energy storage unit (45) and a DC powered load. The energy storage unit is configured to provide to the DC power bus (42) a quantity of DC power via the DC/DC converter (430) of the first VCU in accordance with control exerted thereon by the local controller (431) of the first VCU and a DC powered load. The DC powered load is configured to receive from the DC power bus a quantity of DC power via the DC/DC converter of the second VCU in accordance with control exerted thereon by the local controller of the second VCU.
