ABSTRACT:
A semiconductor device comprises a voltage-driven switching element having a cathode and an anode, in which a voltage is to be applied between the cathode and anode, a power-supply circuit connected between the cathode and anode of the voltage-driven switching element and comprising capacitors, resistors and a reverse current-low preventing diode, for generating an intermediate voltage, a charging switching element for charging a gate of the voltage-driven switching element, using the intermediate voltage generated by the power-supply circuit, a discharging switching element for discharging the gate of the voltage-driven switching element, and a photovoltaic element for generating a photovoltaic power to control to drive the charging switching element and the discharging switching element.
