Abstract

This paper presents the analysis of the gate-source voltage of the gallium nitride high electronic mobility transistor (GaN HEMT) in the half bridge structure focused on the mutual effects of two switching operation. Especially low side gate-source voltage is analyzed mathematically according to the high side switch turn-on and turn-off operation. Moreover, the influence of each gate resistance and parasitic component on the switching characteristic of other side switch is investigated, and the formula, simulation and experimental results are compared with theoretical data.
