Highly efficient DC/DC converter for electric and hybrid vehicle applications

Inmotion's 2nd generation DC/DC converter features a robust design, a wide range of input voltages and, with an adjustable secondary voltage for 12 and 24 V systems, it is ideal for hybrid/electric vehicle applications. All models are available with CAN bus communication in order to seamlessly integrate into the vehicle control system.

  • Best in class quality and reliability achieved through superior design and manufacturing processes
  • Insulation between primary and secondary voltage
  • Rugged IP6K9K design suitable for the demanding environment of electric vehicles
  • Field proven control SW platform used for both industrial and on-road vehicles
  • High efficiency (up to 95%) using Silicon Carbide (SiC) technology

 

  • Documentation in accordance with AIAG PPAP standard
  • Extensive and powerful event handling and data logging simplifies troubleshooting and ensures minimized vehicle down time
  • Liquid (WEG) cooling for minimized physical size
  • Adjustable output voltage and current output limitation
  • Possible to parallel multiple units to achieve higher delivered power at secondary voltage
