The main feature of the hybrid electric vehicle (HEV) that helps to save fuel consumption is the electric motor drive. In the HEVs, there are several confgurations in the propul-sion systems (ex. electric motor assist or fully electric motor drive during start). The main confguaration, the inverter system, is required to deliver powerful and efcient drive to the electric motor. In sophisticated electric motor drive systems, there should be a system to provide regenerative braking and transfer of energy back to the storage system via the battery charging process. The system will function as both an inverter for electric motor propulsion and con-verter/generator for the battery charging process.Optocoupler Capabilities for Hybrid Electric Vehicle Electric Motor Inverter Applications White Paper The main feature of the hybrid electric vehicle (HEV) that Avago’s ACPL-312T gate drive R2Coupler is capable of de- helps to save fuel consumption is the electric motor drive. livering peak output current of 2.5A that can direct drive In the HEVs, there are several configurations in the propul- the insulated gate bipolar transistor (IGBT) in the inverter sion systems (ex. electric motor assist or fully electric motor system up to 1200V/100A.
