Abstract

A transportation refrigeration system (101) is provided and includes a trailer refrigeration unit (TRU) (110), a battery (120) to provide electricity for the TRU (110), an electrical system (140) and a controller (160). The electrical system (140) includes a direct current (DC) bus (141) electrically interposed between the battery (120) and the TRU (110). The electrical system (140) further includes an inverter (142) and a boost converter (143) disposed on the DC bus (141). The controller (160) includes a memory unit (202) storing first, second and third efficiency tables (181, 182, 183) for the TRU (110), the inverter (142) and the boost converter (143), respectively, and a processor (201. The processor (201) sets an operational target for the TRU (110) and achieves the operational target by controlling the inverter (142) and the boost converter (143) according to a voltage of the battery (120), the first, second and third efficiency tables (181, 182, 183) and real-time operating conditions.
