Inverter safety facilities and prices

As vehicle manufacturers pivot to electronic systems like traction inverters, so must the coverage of such systems by our safety standards. While traditional "product safety" refers to the elimination of risk from electrical shock, fire and mechanical hazards, "functional safety" specifically refers to electrical and electronic system hazards.

NXP has developed a functional safety concept for an HV traction inverter that addresses these two points. It defines several system deliverables that customers can use to build their own concept more quickly.

Focuses on vehicular electric power systems analysis, design, prototyping and testing to meet functional safety needs. The power inverter controls energy conversion between an electric source (e.g. battery) and the mechanical shaft of the pmsm motor based on torque requested from Vehicle Control Unit (VCU).

In the example of an HV inverter for EVs, the functional assumption could be resumed as follows: an inverter is the main traction system of an electric vehicle. It controls energy conversion between an electric source (HV DC battery) and the mechanical shaft of the electric motor, based on torque requested from the vehicle control unit (VCU).

In the automotive space specifically, the use of highly-configurable isolated gate drivers in traction inverter systems is growing as a means to improve EV performance and streamline functional safety certification.
