Abstract
In a driving apparatus of a power semiconductor element for conducting or interrupting a main current, first resistance variable for changing a first resistance according to a control voltage, and second resistance variable for changing a second resistance according to a voltage between a first and a second terminal are provided, and either one of a voltage of a control power supply or a voltage between the first and the second terminal is voltage-divided by the first resistance and the second resistance, and the divided voltage is applied to a control gate terminal at the time of conducting or interrupting the main current.
