Overview

 Kia EV6 GT was released in 2022 by Kia Motors (Kia Corporation), a subsidiary of Hyundai Motors, and this car is the first high-performance BEV (battery electric vehicle).

The range is 423km and the maximum speed is 260km/h.

This report is the detailed circuit analysis report of the rear inverter PCB.

Product characteristics

  • Motor is Open-end Winding Motor
  • Three types of power modules are used.

  (1) ON Semiconductor SiC MOSFET(1200V, Half-Bridge)※

  (2) Infineon Si IGBT(1200V, Half-Bridge)

  (3) Infineon Si IGBT(1200V, Bi-Directional Switch) 

  • The car uses a 2-stage motor system.

     High efficiency mode driven by (1) and (3), and high output mode in which dual inverters

     are configured by (1) and (2). Boost the voltage from 400 V to 800 V using (1) and (2) and a

      motor when charging quickly.

  • Three NXP MCUs are used.
  • Gate Driver is ROHM’s BM60061FV-C (with built-in switching controller).

 

Module and SiC Structure analysis report and SiC process flow analysis report are available. (Report No:23G-0469-1,2)
