Gate Drive Optocouplers for HEV Electric Motor Inverters
29 June 2011 | Source: Independent Resources
Hybrid electric vehicles (HEVs) save fuel because of their
electric motor drive. In an HEV, the propulsion system can
be configured several ways, for example in the electric
motor assisted mode or in the fully electric motor drive
For electric motor drive an inverter system is required to
deliver powerful and efficient drive to the electric motor.
In sophisticated electric motor drive systems there should
be a regenerative braking system that transfers energy
back to the battery storage system via a charging process.
The system will function as both an inverter for electric
motor propulsion and as a converter/generator for the
battery charging process.
