TRANSPORT REFRIGERATION UNIT (TRU) DIRECT CURRENT (DC) ARCHITECTURE

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