Abstract: A temperature measuring apparatus is provided which includes a sensor assembly made up of sensing devices which are connected together to produce an output signal correlated with the temperature of a target object. The temperature measuring apparatus determines the number of the sensing devices of the sensor assembly and corrects the output signal so as to compensate for an error in determining the temperature of the target object which depends upon the number of the sensing devices.

Abstract: An inverter for driving a motor generator has series connection units, each of which has two switching elements, connected in series, in high and low voltage sides, respectively. A drive unit is arranged for each switching element. A gate of the switching element is connected to an emitter thereof through a first cutoff resistance and a first cutoff switching element in the drive unit. The gate of the switching element is also connected to the emitter thereof through a second cutoff resistance and a second cutoff switching element in the drive unit. A resistance value of the first cutoff resistance is higher than a resistance value of the second cutoff resistance. A software cutoff process is performed when the switching element is in a completely turned-on state so that the first cutoff switching element is turned on and the second cutoff switching element is turned off.

Abstract: In an error correction device, a frame generation section receives pulse signals as temperature information of a power switching element transmitted from a PWM comparator. The frame generation section sets a first correction pulse signal, a second correction pulse signal and the temperature information sequentially into each frame. A pulse width of the first correction pulse signal corresponds to a pulse width when a time ratio thereof becomes 100%. A pulse width of the second correction pulse signal corresponds to a pulse width when a time ratio thereof becomes 50%. A microcomputer receives the temperature information through a photocoupler and corrects the received temperature information. The microcomputer calculates a temperature detection value of the power switching element on the basis of the corrected temperature information.

Abstract: A first-path connects an input-terminal and an output-terminal of a high-potential-side switching-element and includes a high-potential-side rectifying-device and a high-potential-side passive-element. A second-path connects the output-terminal of the high-potential-side switching-element and the output-terminal of a low-potential-side switching-element and includes a low-potential-side rectifying-device and a low-potential-side passive-element. A high-potential-side applying-unit applies voltage to a connecting point between the high-potential-side rectifying-device and the high-potential-side passive-element. A high-potential-side determining-unit determines that an overcurrent is flowing between the input-terminal and the output-terminal of the high-potential-side switching-element by using a first-value. A limiting-unit limits a current between the low-potential-side rectifying-device and the output-terminal of the high-potential-side switching-element if the overcurrent is flowing. A low-potential-side applying-unit applies voltage to a connecting point between the low-potential-side rectifying-device and the low-potential-side passive-element. A low-potential-side determining-unit determines that an overcurrent is flowing between the input-terminal and the output-terminal of the high-potential-side or low-potential-side switching element by using a second-value.

Abstract: In a drive unit for a reverse-conducting switching element which is a driven switching element, a process to transfer electric charges to a conductive control terminal of the driven switching element is performed on the basis of a turn-on command or a turn-off command, thereby turning on and off the driven switching element. A transfer rate of the electric charges is changed in a period from when the transfer of the electric charges to the conductive control terminal is started until when it is completed. While judged that forward current flows in a free-wheel diode, the electric charges are inhibited from being charged to the conduction control terminal which corresponds to the free-wheel diode in which the forward current is judged to flow. While the electric charges are inhibited from being charged to the conductive control terminal, a change of the transfer rate is disabled.

Abstract: In a driver, a charging module stores negative charge on the gate of a switching element via a normal electrical path to charge the switching element upon a drive signal representing change of an on state to an off state. This shifts the on state of the switching element to the off state. An adjusting module changes a value of a parameter correlating with a charging rate of the switching element through the normal electrical path as a function of an input signal to the driver. The input signal represents a current flowing through the conductive path, a voltage across both ends of the conductive path, or a voltage at the gate. A disabling module disables the adjusting module from changing the value of the parameter if the drive signal represents the on state of the switching element.
