An embodiment of a system for multiple source power conversion is implemented in a vehicle that includes an alternating current (AC) power source and first and second direct current (DC) power sources. The system includes an inverter, a DC-to-DC converter, and a controller. The controller receives external commands, inverter feedback signals, and DC-to-DC converter feedback signals, and executes and inverter control algorithm and DC-to-DC converter control algorithm. An embodiment of a method for multiple source power conversion between an AC power source, and first and second DC power sources includes receiving external commands from a remote source, inverter feedback signals from an inverter, and DC-to-DC converter feedback signals from a DC-to-DC converter. The method also includes executing an inverter control algorithm and a DC-to-DC converter control algorithm to generate drive signals for the inverter and DC-to-DC converter, respectively, based on the received commands and feedback signals.

What is claimed is: 1. A system for multiple source power conversion in a vehicle that includes a first direct current (DC) power source, a second DC power source, and an alternating current (AC) electric motor that functions as a traction device of the vehicle, the system comprising:an inverter having a plurality of first switches, a first DC input/output (I/O) connector, a second DC I/O connector, and an AC I/O connector, wherein the first DC I/O connector is coupled with the second DC power source, and the AC I/O connector is coupled with the AC electric motor, and wherein the the first switches are controllable to convert DC power received via the first DC I/O connector from the second DC power source into AC power, which is provided to the AC electric motor;a DC-to-DC converter having a plurality of second switches, a third DC I/O connector, and a fourth DC I/O connector, wherein the third DC I/O connector is coupled with the second DC I/O connector of the inverter, and the fourth DC I/O connector is coupled with the first DC power source; anda single controller coupled to the inverter and the DC-to-DC converter, wherein the single controller receives external commands, inverter feedback signals, and DC-to-DC converter feedback signals, and executes a first control algorithm for controlling the first switches of the inverter and a second control algorithm for controlling the second switches of the DC-to-DC converter based on the external commands, the inverter feedback signals, and the DC-to-DC converter feedback signals, wherein the single controller executes the first and second control algorithms in a cyclic manner in which, during a single switching cycle of the first and second switches, the single controller executes a portion of the first control algorithm to generate first drive signals for the first switches of the inverter and executes a portion of the second control algorithm to generate second drive signals for the second switches of the DC-to-DC converter, and wherein the controller generates the first and second drive signals so that the first switches of the inverter and the second switches of the DC-to-DC converter are synchronized to switch at a same frequency and out of phase.
