Assignee: TRANSPORTATION IP HOLDINGS, LLC
Field: Transport (Mechanical engineering)
Classification: CPC B  H  Y | IPC B  H

Claim 0:
1. A power unit comprising:
a power converting subunit configured to receive a current from a second power unit, the power converting subunit configured to be operably coupled with the second power unit and a load;
a filter comprising one or more inductors and a first capacitor, the filter operably coupled with the power converting subunit;
a sensor configured to measure a phase of a voltage of the power unit and a phase of a voltage of the second power unit received by the power unit, wherein the phase of the voltage of the power unit is not communicated to the second power unit and the phase of the voltage of the second power unit is not communicated to the power unit; and
a control unit operably coupled with the power converting subunit, the control unit configured to control operation of the power converting subunit based on the current received from the second power unit and a voltage received from the first capacitor, the control unit configured to control a current of the power unit to share a quantity of electrical output current flowing to the load with the second power unit without the control unit communicating between the power unit and the second power unit,
wherein the control unit is configured to change an operation of the power converting subunit to change an amount of electric output current generated by the power converting subunit based on an amount of electrical output current received from the second power unit.
