The traction inverter converts energy from the vehicle's battery in order to drive the motors in the drivetrain. This key component has a direct impact on road performance, driving range and reliability of the vehicle also as a consequence of their weight and size.
Subject to all the possible stress found in a road vehicle from heat and vibrations, these converters must be able to handle high power and currents along with the associated Electro Magnetic Compatibility (EMC) challenges as well as provide fail-safe operation to ensure dependability and safety for the driver and passengers.
To help developers increase the automotive inverter's power efficiency and reduce size and weight, ST has a wide offer of discrete semiconductors including AEC-Q101 qualified IGBTs and both silicon and silicon-carbide (SiC) MOSFETs and diodes, AEC-Q100 qualified galvanically isolated IGBT and MOSFET gate drivers and SPC5 32-bit automotive microcontrollers for designing scalable, cost-effective and energy-efficient EV traction inverter solutions.
