AC inverters for 24-80V electric vehicle applications

AC Superdrive (ACS) is a family of inverters with power levels from 5 to 50kVA , designed for nominal voltages between 24V and 80V. The ACS is developed with traction, hydraulic pump and generator applications in mind which makes it an ideal choice for most battery-powered electric vehicles.

In addition to CAN bus communication, all ACS models are available with optional I/O to facilitate distribution of vehicle control functionality in a larger control system, or for stand-alone operation.


  • Best in class quality and reliability, achieved through superior design and world class manufacturing processes
  • Rugged design suitable for the demanding environment of electric vehicles. Protected against ingress of dust and water to IP65.
  • Powerful ARM processor and operating system allows parallel execution of customized vehicle control tasks and motor control tasks
  • I/O version allows vehicle control to reside in the ACS, directly interfacing vehicle sensors and actuators
  • Software Quality is assured through development and review processes compliant to Automotive SPICE®
  • Industry standard CANopen and J1939 protocols for reliable communication in the vehicle
  • Extensive and powerful event handling and data logging simplifies troubleshooting and minimizes vehicle down time
  • Supports AC induction, AC synchronous, brushless DC motors. Selected models have optional DC motor output
  • Standard firmware with built-in support for traction, pump or generator applications, including functions such as hill-hold, programmable braking/acceleration characteristics, dual-traction, and best performance curve
  • Peer to peer communication allows master-less communication between nodes on CAN bus
  • Auto tuning functionality for pairing the controller with a motor already installed in a vehicle
  • Limitation of the output as a function of motor speed, motor and controller temperature, battery voltage, DC power and/or motor torque to protect powertrain components
  • State of the art vector control with optimal efficiency throughout the full speed range
