  • Longer range per charge
  • Faster charging
  • Higher power density
Electric vehicle features

On-board charger

As more electric vehicles enter the market, OEMs and Tier 1s will be challenged to provide on-board charging solutions that can support multiple regions with different power grid infrastructures.  C2000 offer OEMs and Tier 1s the ability to scale across a wide power range with the same software code base.  

Features

  • Advanced topology support for high-efficiency and low THD
  • Scalable portfolio for modular or integrated design

Benefits

  • Enables EV range
  • Enables faster charging

Automotive HVAC compressor module

InstaSPIN-FOC™ is a sensorless motor control solution ideal for compressors and auxiliary motors within the vehicle.  With motor parameter identification and automatic tuning, even those new to advanced motor control can have high performance control within minutes.  InstaSPIN motor control solutions can provide full torque at low speeds (<500rpm) which reduces power usage, increases overall efficiency, and allows for use of smaller, more compact motor designs.

Features

  • <400 rpm full torque to high speed
  • InstaSPIN-FOC motor control solutions

Benefits

  • Increased dynamic range
  • Increased overall efficiency and use of smaller, more compact motor designs
