Evaluating GaN Switches: The Design Tradeoffs Shaping Next-Gen EV Power Electronics

Gallium nitride (GaN) semiconductors offer superior switching speeds and compact efficiency for electric vehicle inverters and onboard chargers, but integrating them introduces steep engineering challenges. A closer analysis highlights the delicate balance between gate-drive management, parasitic inductance, and board layout when handling ultra-fast transient voltages. Successfully navigating these physical constraints will be crucial for automakers seeking to minimize thermal losses and maximize electric driving range.
