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 an optimal integration into the target vehicle, with Inmotion's proprietary PLASMA software platform.

With a rugged design, 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
  • Optional adapter kit for pre-assembly of shielded high voltage cables
