The subject matter of the invention is a system and method for operating a variable frequency drive in a transport refrigeration unit using an AC power source. A system in a transport refrigeration unit (TRU) for driving a compressor and/or fan (s) of the TRU by a variable frequency drive (VFD) operable using AC power includes the VFD operatively connected between the compressor and one or more AC power sources, such as an engine-generator assembly and/or a power grid of the TRU. The same VFD or a different VFD is also operatively connected between the AC power source and the fan (s) associated with the evaporator and condenser of the TRU. The VFD is configured to be operated by an AC power source. The VFD is operable to receive three-phase AC power ranging from 200 to 650 volts and 0.25 to 25 KW from at least one of the AC power sources, and convert the received three-phase AC power to supply AC power or DC power to a motor associated with the compressor and/or fan (s).

    本发明的主题是“用于在运输制冷单元中使用AC功率源操作变频驱动器的系统和方法”。一种在运输制冷单元(TRU)中用于通过可使用AC功率来操作的变频驱动器(VFD)驱动TRU的压缩机和/或(一个或多个)风扇的系统包括操作地连接在压缩机和诸如TRU的引擎‑发电机组合件和/或电力网的一个或多个AC功率源之间的VFD。相同的VFD或不同的VFD也操作地连接在AC功率源和与TRU的蒸发器和冷凝器相关联的(一个或多个)风扇之间。VFD被配置成由AC功率源操作。VFD可操作用来从AC功率源中的至少一个接收范围从200到650伏特和0.25到25KW的三相AC功率,转换接收的三相AC功率以向与压缩机和/或(一个或多个)风扇相关联的马达供应AC功率或DC功率。
