    摘要: The object of the invention is to provide an inverter system and vehicles using this inverter wherein accurate detection of the abnormal heat generation from the inverter is ensured, despite a large amount of noise signals, a substantial fluctuation in environmental temperature, or a change of cooling performances resulting from the environmental conditions. Based on the output value of an outside air temperature detecting means 150 and temperature calculation parameters inputted from outside the inverter system, the temperature calculation circuit 144B of an error detecting section 144 calculates the temperature Tcal where a temperature detecting means below semiconductor device 152 is installed. A calculation approximate line calculation circuit 144C works out the approximate curve of the difference between the theoretical temperature value and the real temperature value Treal detected by a temperature detecting means below semiconductor device 152, and captures the trend of the temperature difference, using a periodic sampling method, whereby a error determining circuit 144E determines an error, based on the difference from the initial trend obtained in advance or change of the trend.

    摘要: In such a product that torque of a motor is continuously generated when a rotation number of the motor is nearly equal to zero, since an output voltage is kept at a constant value in accordance with a rotation position of the motor, such a condition that currents are concentrated in a specific element are maintained. As a result, a temperature of the specific element is increased, so that there are problems that a temperature fail of an inverter apparatus may readily occur, and thus, lifetimes of elements are lowered. In a power converter of a motor drive apparatus, windings are energizing-controlled in such a manner that only 1 phase of a switching circuit is pulse-width-controlled when the motor is under motor locking condition.
