Silicon vs Gallium Nitride: The Chain Reaction Created by Switching Speed
Silicon vs Gallium Nitride: The Ripple Effect of Switching Speed
Why a Wider Bandgap Leads to Smaller Transformers Inside Chargers
Silicon
1.1 eV Bandgap (Energy Barrier)
About 65 kHz Standard Switching Frequency
Requires Larger Transformers and Magnetic Components
Gallium Nitride
3.4 eV Bandgap (Energy Barrier)
130~300 kHz Achievable Switching Frequency
Significantly Reduced Transformers and Magnetic Components
