Abstract
Systems and methods are disclosed of an engine driven power system that includes a permanent magnet generator electrically connected to an energy storage device. An air compressor is coupled to the permanent magnet generator via a clutch. A controller provides power from the energy storage device to the permanent magnet generator to turn the permanent magnet generator to drive the air compressor via the clutch to increase an air pressure level.
Claims17
An engine driven power system, comprising:
- a permanent magnet generator electrically connected to an energy storage device;
- an air compressor coupled to the permanent magnet generator via a clutch;
- a pressure sensor configured to measure an air pressure level;
- and
- a controller configured to:
- provide power from the energy storage device to the permanent magnet generator to turn the permanent magnet generator to drive the air compressor via the clutch to increase the air pressure level;
- and
- control the energy storage device to provide power to the permanent magnet generator when the air pressure level drops below a threshold low-pressure level.

An engine driven power system, comprising:
- a permanent magnet generator electrically connected to an energy storage device;
- an air compressor coupled to the permanent magnet generator via a clutch;
- wherein the engine is detachably coupled to the permanent magnet generator via a second clutch;
- and
- a controller configured to:
- monitor a speed of the engine;
- provide power from the energy storage device to the permanent magnet generator to turn the permanent magnet generator to drive the air compressor via the clutch to increase an air pressure level;
- and
- control the permanent magnet generator to couple with the engine via the second clutch in response to the engine speed increasing above a threshold level such that the engine drives the permanent magnet generator.
