    • PROBLEM TO BE SOLVED: To provide an inverter apparatus capable of stably controlling a torque or a switching frequency, even when a motor is driven at a low-speed rotation and a temperature in a switching element is fructuated. SOLUTION: A filter processor 13 performs filtering to the temperature value of the switching element detected by a temperature sensor 11 and a temperature detecting circuit 12, and provides the temperature of the switching element after passing through a filter (block 22-24). A torque limiter 14 regulates an input torque-commanding value, based on the temperature value of the switching element after passing through the filter. A gate generator 15 controls the inverter apparatus on the basis of the torque-commanding value regulated by the torque limiter 14. COPYRIGHT: (C)2010,JPO&INPIT
