摘要： PROBLEM TO BE SOLVED: To provide a novel temperature sensing device capable of suppressing deterioration of temperature sensing accuracy of switching elements Sw# by correcting values Vf detected by temperature sensing diodes Tw# (#=p,n).SOLUTION: A temperature detection circuit of a switching element Sw# includes a temperature sensing diode Tw# and a thermistor 38 for sensing temperature of the switching element Sw#. A possible range of error inherent in a value Vs detected by the thermistor 38 is smaller than a range of possible error inherent in a value Vf detected by the temperature sensing diode Tw#. When it is determined that the switching element Sw# is yet to be driven and temperature at the thermistor 38 is not in a low temperature range in such configuration, a correction value for correcting the value Vf detected by the temperature sensing diode Tw# is computed based on the value Vs detected by the thermistor 38. The value Vf detected by the temperature sensing diode Tw# is then corrected using the computed correction value.

摘要： PROBLEM TO BE SOLVED: To solve such a problem that, when noise is superimposed on a transmission path of a sense voltage Vse2, regardless of a fact that a collector curent of a switching element S¥# does not decrease, the collector current may be regarded as decreasing and impedance of a discharge path may be controlled to increase.SOLUTION: With switching of an operation signal g¥# of a switching element S¥# from an on-operation command to an off-operation command, a switching element 26 for constant current is off-operated and a first switching element 30 for discharge is on-operated. With increasing of a sense voltage Vse2 to a determination voltage Vths or higher, the first switching element 30 for discharge is off-operated and a second switching element 34 for discharge is on-operated. This switching based on the sense voltage Vse2 is prohibited until a gate voltage Vge becomes a specified value or lower.

摘要： PROBLEM TO BE SOLVED: To solve the problem that, if noise is superposed on a transmission path for a signal indicating to the effect that a collector current has decreased, a discharge path with a high resistance value (a path incorporating a resistor 34) could erroneously be put in a closed state assuming that the collector current has decreased although it actually did not decrease.SOLUTION: When an operation signal g¥# for a switching element S¥# is switched to an off operation command, a first discharge switching element 32 is subsequently switched on, whereby the gate of the switching element S¥# is connected to the emitter via a discharge resistor 30 and the first discharge switching element 32. Thereafter, as a current flowing in the switching element S¥# decreases, the first discharge switching element 32 is switched off on the basis of a sense voltage Vse and also a second discharge switching element 36 is switched on. The sense voltage Vse serving as an input signal for this switching process is enabled only when the operation signal g¥# is an off operation command.
