Tackling key challenges of e-motors

OEMs are striving to increase the efficiency of the e-motor/inverter by tackling many challenges:

  • Deliver a high-efficiency all across the eMotor torque/speed operating range
  • Deliver a wider operating range with higher torque and speed range
  • Deliver more power with less rare earth material and with less costs
  • Reduce the transmission / speed reducer needs and costs
  • Rapid fault detection and response time assuring highest levels of safety for the consumer

SIC INVERTER Reference Design with CISSOID

Up until now, customers only really had 2 options. The first was to develop all the hardware, then integrate with third party software into their design environment. This was extremely time consuming and required in depth knowledge of SiC-based power system design. The second option was to buy an off-the-shelf inverter that, however, does not offer the ability to fully customise for the application requirements. Now this reference design offers the best of both worlds: fast prototyping and adaptable to the application requirements.

  • 1200V SiC-based power module
  • Up to 350kW/850V operation
  • Integrated Gate Driver board
  • Control board with ultra-fast OLEA T222 FPCU
  • Supports both SVPWM and DPWM
  • ISO26262 ASIL Level D ready
  • DC and phase current sensors
  • DC link capacitor & EMI filter
  • Liquid cooling
