Abstract:
1. An inverter apparatus comprising: an inverter including a plurality of pairs of switching elements, each of the pairs of the switching elements being electrically connected to a direct current power source; a rotational speed detecting component that detects a rotational speed of a motor that is electrically connected to the pairs of the switching elements; and a control component that controls an on-off status of the switching elements to convert a direct current electric power from the direct current power source into alternating current electric power, the control component further alternately executing a first switching control and a second switching control during a period in which the rotational speed is detected as being larger than a prescribed rotational speed, the first switching control turning on all of the switching elements of the pairs of the switching elements connected to a positive electrode of the direct current electric power source and turning off all of the switching elements of the pairs of the switching elements connected to a negative electrode of the direct current electric power source, and the second switching control turning on all of the switching elements of the pairs of the switching elements connected to the negative electrode of the direct current electric power source and turning off all of the switching elements of the pairs of the switching elements connected to the positive electrode of the direct current electric power source.
