要約(英語): This paper investigates a switching operation when a current-source gate drive circuit is used for large gate capacitance. The current-source gate drive circuit consists of a voltage source, an input inductor, and switching devices such as an H-bridge inverter. The power consumption of this circuit is reduced in comparison with that of a conventional voltage source gate drive circuit because the energy of the capacitor between a gate and a source is not consumed in gate resistance, which is not required for the current source gate drive circuit. The switching operation of the proposed current source gate drive circuit in the high-frequency inverter is evaluated experimentally. In addition, the power consumption is measured when the switching frequency is changed from 100kHz to 1MHz. As a result, it is confirmed that the power consumption of the current-source gate drive circuit is reduced by 62% compared with that of the voltage source gate drive circuit at 1MHz.
