Abstract
Methods and systems for power management using a power converter in transport are provided. In one embodiment, the method includes monitoring a varying AC input to the power converter. The method also includes calculating a power factor adjustment based on the monitored varying AC input. Also, the method includes a power converter controller adjusting the power converter based on the calculated power factor adjustment to cause the power converter to supply a reactive current to a varying AC load.
Claims19
A method for power management using a power converter in transport, the method comprising:
- an AC distribution network receiving power from a power source;
- the AC distribution network distributing a varying AC power signal;
- a varying AC load receiving the varying AC power signal from the AC distribution network;
- the power converter receiving the varying AC power signal from the AC distribution network, converting the varying AC power signal into a DC power signal, and supplying the DC power signal to a varying DC load;
- a power management system monitoring a varying AC input to the power converter;
- the power management system calculating a power factor adjustment based on the varying AC input;
- and
- a power converter controller adjusting the power converter based on the calculated power factor adjustment to cause the power converter to supply a reactive current to a varying AC load.

A power management system for use in transport, the power management system comprising:
- an AC distribution network that is configured to receive power from a power source, the AC distribution network further configured to distribute a varying AC power signal;
- a varying AC load that receives the varying AC power signal from the AC distribution network;
- and
- a power converter that is configured to receive the varying AC power signal from the AC distribution network, convert the varying AC power signal into a DC power signal, and supply the DC power signal to a varying DC load, wherein the power converter includes a power converter controller that is configured to control operation of the power converter,
- wherein the power management system is configured to monitor a varying AC input to the power converter and calculate a power factor adjustment based on the monitored varying AC input, and
- wherein the power converter controller is configured to adjust the power converter based on the calculated power factor adjustment to cause the power converter to supply a reactive current to the varying AC load.

A transport refrigeration system comprising:
- a refrigeration circuit that includes a compressor;
- a transport refrigeration system controller that is configured to control operation of the transport refrigeration system;
- and
- a power management system that provides power to the transport refrigeration system, wherein the power management system includes:
- an AC distribution network that is configured to receive power from a power source, the AC distribution network further configured to distribute a varying AC power signal,
- a varying AC load that receives the varying AC power signal from the AC distribution network, and
- a power converter that is configured to receive the varying AC power signal from the AC distribution network, convert the varying AC power signal into a DC power signal, and supply the DC power signal to a varying DC load, wherein the power converter includes a power converter controller that is configured to control operation of the power converter,
- wherein one of the transport refrigeration system controller and the power converter controller is configured to monitor a varying AC input to the power converter,
- wherein one of the transport refrigeration system controller and the power converter controller is configured to calculate a power factor adjustment based on the monitored varying AC input,
- wherein the power converter controller is configured to adjust the power converter based on the calculated power factor adjustment to cause the power converter to supply a reactive current to the varying AC load.
