Video: Compressed Air Powers Hybrid Engine
Freescale Semiconductor demonstrated an air-electric hybrid at the recent Convergence 2012 conference in Detroit.
November 5, 2012
Freescale Semiconductor showed off a unique hybrid powertrain that combines an air engine with an electric motor assist at the recent Society of Automotive Engineers Convergence 2012 conference in Detroit.
"It's our version of a zero emissions vehicle," Neil Krohn of Freescale Semiconductor told us. The engine and electric assist could be used to power a small vehicle.
As you can see in this video, Freescale starts the air engine with the electric motor and then employs the motor's power again when the situation calls for it. "We bring the electric motor in and overdrive the engine, so now we have an assist for acceleration," Krohn said.
The electronics used to run the hybrid powertrain include a Power Architecture microcontroller, insulated gate bipolar transistors, and gate drive ICs from Freescale, as well as a 40kW inverter from Fuji Electric.
