Abstract
An inverter apparatus basically includes an inverter, a rotational speed detecting component and a control component. The inverter includes a plurality of pairs of switching elements. The control component controls an on-off status of the switching elements to convert a direct current from a direct current power source into alternating current by alternately executing first and second controls when a rotational speed of a motor connected to the switching elements is larger than a prescribed rotational speed. The first control turns on the switching elements that are directly connected to a positive electrode of the power source, and turns off the switching elements that are directly connected to a negative electrode of the power source. The second control turns on the switching elements that are directly connected to the negative electrode and turns off the switching elements that are directly connected to the positive electrode.
