Assignee: CARRIER CORPORATION
Field: Electrical machinery, apparatus, energy (Electrical engineering)
Classification: CPC H  F | IPC F  H

Claim 0:
1. A transport refrigeration device comprising a refrigeration unit, a refrigeration unit controller, and a power regulating unit for converting an AC input to a DC output, the power regulating unit comprising:
a rectifier module configured to perform a rectification operation on the AC input to obtain a first DC signal;
a controller configured to control the rectification operation of the rectifier module based on corresponding parameter information for reflecting fluctuations of the AC input to prevent the first DC signal obtained from being affected by the fluctuations;
a first output port configured to output the first DC signal, wherein the first output port of the power regulating unit outputs a first DC signal to the refrigeration unit to supply power to the refrigeration unit;
a first DC-DC conversion module separate from the rectifier module, the first DC-DC conversion module configured to convert the first DC signal into a second DC signal;
a second output port separate from the first output port, the second output port configured to output the second DC signal;
wherein the second output port of the power regulating unit outputs a second DC signal for charging a high-voltage battery pack, and wherein the high-voltage battery pack is a dedicated battery pack provided in the transport refrigeration device;
a second DC-DC conversion module configured to convert the first DC signal into a third DC signal; and
a third output port configured to output the third DC signal.
