ACH

High power inverter for hybrid and electric vehicles

ACH is a family of inverters, designed for nominal voltage levels from 100 V to 750 V and with continuous power levels of up to 300 kVA. The inverter functionality is easily customized for a optimal integration into the target vehicle, with Inmotions proprietary PLASMA software platform.

With a rugged design and an expected life time of over 60 000 hours, the ACH is the ideal choice for both on-highway and off-highway applications.

 

  • Best in class quality and reliability, achieved through superior design and world class manufacturing processes, backed up by field experience
  • Rugged IP6K9K design suitable for the demanding environment of electric vehicles
  •  4-quadrant, synchronous or asynchronous AC motor control, with speed, torque and DC-voltage control modes
  •  Field proven control SW platform used for onhighway and off- highway vehicles
  • Software quality is assured through development and review processes designed for compliance with Automotive SPICE©
  • CAN communication, J1939 and/or CANopen with support for diagnostics and software download
  • With continuous power levels up to 300 kVA, the ACH is ideally suited for hybrid as well as fully electric vehicle applications
  • Nominal voltage 350 and 650 V. Fully operational from 100 to 750 V bus voltage
  • Liquid (WEG) cooled
  • Automatic protection against overheating and over-voltage
  •  Redundant Discharge of DC-capacitors
  • Internal EMI filtering of the dc-bus eliminates interference with other electronic equipment and allows parallel operation of several ACH controllers
  • Powerful standard firmware features as well as extensive software configurability ensures optimal system functionality
  • Designed for a working life in excess of 60 000 hours
  • Extensive and powerful event handling and data logging simplifies troubleshooting and minimizes vehicle down time
  • Interlock for personal safety
