Abstract
A power delivery system includes a turbocharger assist device and an inverter. The turbocharger assist device is mechanically connected to a turbocharger that is operably coupled to an engine, and is configured to generate electric current based on rotation of a rotor of the turbocharger. The inverter is electrically connected to the turbocharger assist device via a bus, and is configured to receive the electric current generated by the turbocharger assist device via the bus and supply the electric current to power a load.
Claims18
A power delivery system comprising:
- a turbocharger assist device mechanically connected to a turbocharger, the turbocharger operably coupled to an engine and configured to compress air for combustion within the engine, the turbocharger assist device configured to generate electric current based on rotation of a rotor of the turbocharger;
- an inverter electrically connected to the turbocharger assist device via a secondary bus;
- and
- a bridge switch configured to selectively electrically connect the inverter to a primary bus of the power delivery system and electrically isolate the inverter from the primary bus, wherein while the bridge switch electrically isolates the inverter from the primary, the inverter is configured to receive the electrical current generated by the turbocharger assist device and supply the electric current generated to power a load.
A power delivery system comprising:
- a turbocharger assist device mechanically connected to a turbocharger, the turbocharger operably coupled to an engine and configured to compress air for combustion within the engine;
- an inverter configured to electrically connect the turbocharger assist device to a primary bus that receives electric current generated by an alternator;
- and
- one or more processors operably connected to the turbocharger assist device and configured to operate the turbocharger assist device in a motor mode in response to a monitored value of an operating parameter being in a first range, the turbocharger assist device in the motor mode configured to receive electric current from the primary bus via the inverter and generate torque for rotating a rotor of the turbocharger,
- the one or more processors configured to operate the turbocharger assist device in a generator mode in response to the monitored value being in a second range that does not overlap the first range, the turbocharger assist device in the generator mode configured to generate electric current based on rotation of the rotor of the turbocharger, and the inverter supplies the electric current to the primary bus.
A power delivery system comprising:
- a turbocharger assist device mechanically connected to a turbocharger, the turbocharger operably coupled to an engine and configured to compress air for combustion within the engine;
- a DC-DC converter disposed between a primary bus and a secondary bus and configured to convert electric current between a higher voltage level on the primary bus and a lower voltage level on the secondary bus;
- and
- an inverter electrically connected to the secondary bus and disposed between the turbocharger assist device and the DC-DC converter, the inverter configured to receive alternating current (AC) generated by the turbocharger assist device based on rotation of a rotor of the turbocharger, and convert the AC to direct current (DC) that is supplied to the DC-DC converter.
