Advantages >>>

More compact design | GaN chargers are often much smaller and lighter than conventional silicon chargers.

Higher efficiency | They convert electricity more efficiently, generate less heat, and lose less energy.

Faster charging | Thanks to higher power density, they can deliver more watts and charge devices faster (e.g., smartphones, laptops, tablets).

Less heat generation | GaN generates less heat for the same power, which extends the lifespan of the electronics.

For experts >>>

GaN is a wide-bandgap semiconductor, a compound semiconductor with a large band gap, operating at significantly higher frequencies than silicon (MOSFETs and IGBTs). This allows for smaller passive components and increases efficiency. Unlike SiC (silicon carbide), GaN switches faster.

SiC operates at higher voltages than GaN and requires a high gate drive voltage. However, SiC components are in high demand in high-voltage power electronics due to their advantageous high current carrying capacity.
