Zusammenfassung:	A powertrain system includes a multi-link power-split electric power system including first and second electric machines. The first electric machine mechanically rotatably couples to a drive wheel and the second electric machine mechanically rotatably couples to an internal combustion engine. The first electric machine electrically connects in series between first and second inverters. The first inverter electrically connects to a first high-voltage DC electric power bus and the second inverter electrically connects to a second high-voltage DC electric power bus. The second electric machine electrically connects to a third inverter that electrically connects to the second high-voltage DC electric power bus.
