越来越多的电力电子应用使用 GaN 晶体管,因为与传统的 Si 器件相比,它们能够实现更高的开关频率。更快的开关可以缩小无源器件的尺寸,并在可再生能源、电动汽车和家用电器等应用中实现紧凑的解决方案。 GaN 晶体管受益于约 10 倍的较小栅极电荷 QG 和栅极驱动电压(通常为 5V,而 Si 为约 15V)。
More and more power electronics applications utilize GaN transistors as they enable higher switching frequencies in comparison to conventional Si devices. Faster switching shrinks down the size of passives and enables compact solutions in applications like renewable energy, electrical cars and home appliances. GaN transistors benefit from ∼10× smaller gate charge QG and gate drive voltages in the range of typically 5V vs. ∼15V for Si.
