Technical FAQs 4

Are traction inverters covered by safety standards?

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.

What is a safety manager in an inverter?

The inverter shall implement a Safety Manager to collect faults and react to bring the vehicle into a safe state (motor command stopped). The ASIL level and FTTI are associated with the safety requirements derived and inherited directly from the safety goals.

How safe is an EV HV inverter?

In the case of an EV HV inverter, the definition of the safe state is quite complex due to a high amount of energy flowing into the electrical motor. In some cases this can result in unstable behavior instead of ensuring the safe state that is requested by the system.

Do traction inverters need a SiC MOSFET?

Proper design of a low-power auxiliary power supply within traction inverters is critical for ensuring the functional safety of EVs. Learn how SiC MOSFETs can play a critical role in this effort.
