Interview with Dr. Ayman Ayad on Redundant Power Supplies

The power supply for electric and autonomous vehicles is responsible for managing the electrical flow from the battery pack to the motor, in order for the vehicle to function. Electric and autonomous vehicles need a reliable source of power in case of a failure. To ensure this, redundant power supplies are used. These supplies consist of two independent power sources that can provide all the required electrical utilities to an autonomous car, even when one goes down.

Redundancy is a big topic for the industry right now, so we reached out to Dr. Ayman Ayad, Expert for Power Electronics Simulation & System Engineer for HV Electronics in Electrified Vehicles at Vitesco Technologies, to learn more on:

• The design considerations of a redundant power supply system
• The safety standards to be aware of
• Efficiency and optimization
• The types of monitoring and protecting features for a redundant power supply system
