Zusammenfassung:	Embodiments of an electrically powered transport refrigeration unit (TRU) are disclosed. The TRU may include a refrigeration circuit including an electric compressor, an evaporator equipped with an electric blower, and an air cooler equipped with an electric blower. The TRU may also include a control circuit and a power conditioning unit. The power conditioning unit may be used to provide variabledirect current (DC) and/or alternating current (AC) outputs to power elements of the refrigeration circuit, and the control circuit may be used to regulate the variable DC and AC outputs provided bythe power conditioning unit to control operation of the TRU. The electrically powered TRU may be configured to use R774 as a refrigerant. 本发明揭露了一种电动的运输制冷单元(TRU)的实施方式。该TRU可以包括制冷回路，该制冷回路包括电动压缩机、配有电动吹风机的蒸发器、以及配有电动吹风机的气冷器。该TRU还可以包括控制电路和功率调节单元。该功率调节单元可用于给该制冷回路的功率元件提供可变的直流(DC)和/或交流(AC)输出，该控制电路可用于对该功率调节单元提供的可变的DC和AC输出进行调节，从而控制该TRU的工作。该电动的TRU可以被设置成使用R774作为制冷剂。
