HVDC in Hybrid Automotive, Earth-Moving Equipment and Transportation Applications

Moderated by: Stephen Oliver, VP VI Chip Product Line
There has been a rapid move to hybrid power chains in cars, which is also beginning to impact the design of other forms of transportation such as earth moving/construction vehicles, trucks, buses and locomotives. Using diesel engines alone can be very inefficient: research shows less than 15% of the energy in the fuel is used for actual work in earth moving equipment.
Energy is typically stored in Li-Ion battery stacks at 160 V to 420 V, or 800 V for heavy earth-moving equipment, requiring bi-directional HVDC power distribution systems to allow efficient battery charging and power delivery.
By using HVDC power distribution direct to the wheel motors for propulsion and regenerative braking, hybrid vehicles can improve efficiency, whilst reducing size and weight, enabling extended range, higher performance and lower cost. Driving auxiliary functions (e.g. air-con) from more efficient electrical power and switching from hydraulics to electric motors can enable further savings, particularly in earth-moving equipment. This webinar describes these trends, and explains how modern power components simplify the development of HVDC systems for transportation applications.
Participants will learn:
  First-generation approaches to hybrid and electric vehicle design
  Causes of energy wastage in large diesel vehicles
  The benefits of HVDC in transportation applications
  Example HVDC schematics for commercial and industrial land vehicles
  How to use bi-directional converters to enable charging
and regenerative braking vehicles
  How new power components simplify HVDC design in transportation applications

 

Who should attend?
Anyone involved in transportation design, whether heavy earth moving and construction equipment, automotive, rail, busses or trucks, will benefit from attending this webinar.
