Semiconductor element driving apparatus

A semiconductor element driving apparatus comprising:

• a primary circuit to which a plurality of signals including a first control signal controlling driving of a semiconductor element during a normal mode, a second control signal controlling driving of the semiconductor element during an ASC mode, and a transition signal transitioning from the normal mode to the ASC mode, or including the first control signal and a control transition signal corresponding to the second control signal and to the transition signal are input;
• a signal transmission circuit including an insulating element capable of transmitting a signal;
• and
• a secondary circuit that drives the semiconductor element based on a plurality of transmission signals corresponding to the plurality of signals transmitted from the primary circuit through the signal transmission circuit,
• wherein the secondary circuit includes:
• an ASC mode determination circuit that determines whether the normal mode or the ASC mode is executed based on a transmission transition signal corresponding to the transition signal or to the control transition signal among the plurality of transmission signals;
• and
• a logic circuit that drives the semiconductor element based on a first transmission control signal corresponding to the first control signal among the plurality of transmission signals when the ASC mode determination circuit determines that the normal mode is executed, and drives the semiconductor element based on a second transmission control signal corresponding to the second control signal or to the control transition signal among the plurality of transmission signals when the ASC mode determination circuit determines that the ASC mode is executed.
