xEV Inverter

Overview

The Renesas xEV inverter enhances HEV/EV motor performance through its motor parameter calibration tool and practical inverter hardware designs. It achieves this by leveraging a combination of MCUs, a power management IC (PMIC), and gate driver ICs.

System Benefits:

  • Optimized performance with practical inverter specifications for xEV 100kW-class motors.
  • Comprehensive evaluation tools, including a reference solution kit with inverter reference designs, software, model-based designs, and calibration tools to accelerate development.
  • Proactive issue resolution through early issue detection and countermeasures supported by Renesas' motor bench and dedicated engineering support.
  • Compact design, achieving a 3.9L compact volume through highly integrated products and advanced temperature management.
  • Superior power efficiency with up to 99% maximum inverter efficiency.
  • Proven reliability with functionality validated in real car demonstrations.
  • High accuracy with advanced sensor error correction for precise performance.
