Curtiss-Wright’s Industrial Group has announced that it will be attending the Electric & Hybrid Vehicle Technology Expo 2018 where, amongst other innovations, the company will be showcasing its World Traction Inverter (WTI) series.
Offering state-of-the-art technology and innovative design for use in hybrid and pure-electric applications, this new family of traction inverters operates with multiple motor technologies – including AC induction, permanent-magnet synchronous (PMS) and interior permanent-magnet (IPM) types – and offers a high level of self-protection with both current and transistor temperature measuring locally to the IGBTs.
A torque motor-control mode is available for hybrid applications, speed mode for pure-electric applications or DC bus voltage mode. In DC bus mode, the inverter can moderate adverse and damaging voltages resulting from situations including regenerative braking.
The WTI family offers a versatile connection to master control systems by either J1939 or CANbus protocols. A customizable, discrete interface also supports digital, analog and solenoid-drive control options.
