摘要： An IGBT drive circuit is provided with a series regulator and a drive circuit. The series regulator includes a transistor and a control circuit. The control circuit and the drive circuit are integrated as an IC. The transistor is connected to the IC as an external component. Since the control circuit and the drive circuit are integrated, the number of components necessary for the IGBT drive circuit can be reduced. Further, the transistor is excluded from the IC so that radiant heat by the IC can be suppressed whereby an IC package having high heat-radiation characteristics is not necessarily used so that increasing size of the IC is avoided.

摘要： A drive circuit is used for driving a switching element. The drive circuit includes a detection unit and an integrated circuit. The detection unit detects a state of a controlled switching element and outputs a voltage signal corresponding to a detection result of the state. The integrated circuit receives the voltage signal via an input terminal for the detection result and controls the switching element based on the received voltage signal. The input terminal includes at least two input terminals that are connected to each other so as to receive the same voltage signal from the detection unit.

摘要： An electronic system has IGBT, on driving FET and off driving FET connected with the gate of the IGBT, and a control circuit. The on driving FET in an on state supplies electric charge to the IGBT gate. The off driving FET in an on state releases the charge from the GET gate. The control circuit controls each of the on FETs according to a driving signal to be set in the on and off states every switching period of time and to control the voltage at the IGBT gate. When on-failure occurs in the on driving FET set in the on state so as to keep the on driving FET in the on state in spite of control of the control circuit, the control circuit controls a controlled element other than the off driving FET to set the IGBT in the off state.

摘要： An apparatus is provided to drive a voltage controlled switching element having a conduction control terminal. In the apparatus, it is determined whether or not voltage at the conduction control terminal is at a first voltage which is lower than a second voltage and which is equal to or more than a threshold voltage. The second voltage is a voltage provided when the switching element is in a normal on-state thereof. The threshold voltage is voltage at which the switching element is switched on. When it is determined that the voltage at the conduction control terminal is at the first voltage, the switching element is forcibly switched off.
