Abstract
A gate-drive system according to the present invention which transmits a drive signal to a semiconductor switching device, includes: an inverter circuit to supply high-frequency power including a fundamental wave component and plural harmonic components each having different frequencies; a power transmission circuit which is connected to the inverter circuit and transmits the high-frequency power outputted from the inverter circuit; power receiving circuits to individually receive the fundamental wave component and plural harmonic components of the high-frequency power transmitted from the power transmission circuit; and a control circuit to generate the drive signal for the semiconductor switching device on the basis of the plural harmonic components of the high-frequency power received by the power receiving circuits.
