Trio of auto-grade power modules offer 300 combinations

Vicor has developed three automotive-grade power modules that can be used in 300 combinations in 48 V EV systems, writes Nick Flaherty. They cover a bus converter from 800 V to 48 V, an unregulated 48 V to 12 V converter and a regulated 48 V power-supply module.

Deep Insight

Isolation technologies

Nick Flaherty investigates techniques that enable digital controllers to interface safely with high-voltage systems. As automotive designs move to electrification, high-power electronics have become critical components in new electronic drivetrain and battery systems. Communication and control from low-voltage digital devices requires electrical isolation of the high-voltage elements from the low-voltage side, covered by the extra-low voltage (SELV) regulations.
