HEV/EV inverter & motor control

Maximize driving range with the industry's leading performance and most reliable solution for inverter and motor control systems

Browse applications
Traction inverter and motor control systems are critical to enable optimal electric vehicle (EV) performance. To build the next generation of these systems, design engineers must reduce power losses and improve system efficiency to make EVs more reliable, increase drive range and enhance safety. Traction inverter and motor control systems require high computational performance coupled with control features, like those from our embedded processing chips, to work in concert with our isolated gate driver, bias supply and current and voltage sensing technologies. Dynamic output current control allows for the usage of wide bandgap technology such as silicon carbide (SiC). Our products enable EVs to maintain ideal motor torque while improving overall system efficiency.

Why choose TI for traction inverter & motor control systems?


Double the speed of your motor

Achieve longer drive range and a smooth driving experience with a fast control loop that helps to minimize torque ripple and provides smooth speed and torque current profiles to the traction motor.


Improve efficiency and system power density

Enable wide bandgap technology to design higher power systems in the same footprint and weight and gain efficiency across temperature, speed and torque to increase the drive range of the vehicle.


Reduce failure rate and extend inverter lifetime

Enhance system reliability with reinforced rated capacitive isolation technology and early failure detection. Streamline functional safety compliance up to ASIL D with our resources and expertise.

Enabling technologies

Isolated gate drivers

The gate driver provides galvanic isolation between input and output, drives the SiC or IGBT-based three-phase motor half bridges and enables monitoring of and protection against various fault conditions.


  • Improve system-level efficiency: minimize switching and conduction losses that include turnon and turnoff energy.
  • Increase power density: high drive strength helps lower the gate driver’s case temperature, mitigating the need for more expensive heat sinks or additional PCB ground. 
  • Enhance reliability and safety: integrated IGBT/SiC health monitoring identifies early failures in power switches. Optimized diagnostics support highest functional safety rating (up to ASIL-D).

Real-time control MCUs

Enable new architectures in the next generation of electrified vehicles with high-performance real-time control MCUs. These capabilities with < 4-us control loops (including resolver) and compute performance of 3.2k DMIPS enable:

  • Increased driving range: Higher motor speeds (>20,000 RPM) reduce motor size and can extend driving distance per charge.
  • Improved power density and efficiency: Better control loop bandwidth use and support for higher switching frequencies (>20kHz) unlocks the potential to use wide-bandgap technologies such as silicon carbide (SiC). 
  • Streamlined functional safety certification: Functional safety features enable up to ASIL-D/SIL3 compliance, E-Safety Vehicle Intrusion Protected Applications (EVITA) and AUTOSAR support.
