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) that is operable using AC power comprises the VFD (108) operatively connected between the compressor (106-1) and one or more ac power source (110-A, 110-B) such as an engine-generator assembly (110-A) of the TRU and/or an electrical grid (110-B). The same VFD (108) or a different VFD (108) is also operatively connected between the AC power source (110-A, 110-B) and fan(s) (106-B) associated with an evaporator, and a condenser of the TRU. The VFD (108) is configured to be operated by the AC power sources(110-A, 110-B). The VFD (108) is operable to receive a 3-phase AC power ranging from 200 to 650 volts and 0.25 to 25 KW from at least one of the AC power source, convert the received 3-phase AC power to supply AC or DC power to a motor associated with the compressor and/or the fan(s).
