摘要： A driving circuit applies a voltage to a switching element (1) to switch between an ON state and an OFF state. The switching element (1) includes a control terminal, a high-potential terminal, and a low-potential terminal, and is switched between the ON state in which a current flows between the high-potential terminal and the low-potential terminal and the OFF state in which the current does not flow therebetween, depending on the voltage of the control terminal in a case in which a potential of the low-potential terminal is defined as a reference potential. The driving circuit includes a negative-voltage power supply (5) and a voltage changing unit (R2, R3, C1). The negative-voltage power supply (5) applies a negative voltage as the voltage to the control terminal when the switching element (1) is switched from the ON state to the OFF state. The voltage changing unit changes the voltage immediately before the switching element (1) is switched from the OFF state to the ON state to be higher than the negative voltage from the negative-voltage power supply (5) immediately after the switching element (1) is switched from the ON state to the OFF state.

摘要： A power supply control apparatus includes a DC power supply including a positive electrode and a negative electrode, a load electrically connected to the DC power supply, a relay connected to a current path from the positive electrode to the negative electrode through the load in series, a switching device connected to the current path in series, and a controller controlling the relay and the switching device. The controller, in a case in which the current path is to be electrically cut off, switches the switching device to an Off state and then switches the relay to the Off state.

摘要： An anode region 106 is formed on a bottom portion of a trench 105 in which a gate electrode 108 is formed or in a drift region 102 immediately under the trench 105. A contact hole 110 is formed in the trench 105 at a depth reaching the anode region 106. A source electrode 112 is embedded in the contact hole 110 while interposing an inner wall insulating film 111 therebetween. The anode region 106 and the source electrode 112 are electrically connected to each other in a state of being insulated from the gate electrode 108 by the inner wall insulating film 111.
