高频下GaN器件频率相关导通电阻的表征与建模

The switching frequencies of the GaN-based power converters have been pushed to several megahertz and even higher. At such high frequencies, the on-resistances of the GaN devices might be much higher than their dc values, especially for the devices with low on-resistances. The frequency-dependent characteristics of the on-resistance are studied through the electrical and thermal experiments for th...
