Inverter apparatus

An inverter apparatus comprising:

• an inverter that includes three high-voltage side switching elements and three low-voltage side switching elements respectively provided in three phases one by one, and drives a three-phase brushless motor;
• an opening and closing control unit that performs controlling so as to cause an electrical angle of the three-phase brushless motor to pass through an angle corresponding to a first combination, to rotate twice by 120° each time to one side in a rotary direction, and to rotate once by 120° to the other side in the rotary direction thereafter, by sequentially closing four combinations each of which is formed with one among the three high-voltage side switching elements and one among the three low-voltage side switching elements;
• and
• a detection unit that detects a conduction state of a circuit including the closed high-voltage side switching element and the closed low-voltage side switching element,
• wherein all the three high-voltage side switching elements and the three low-voltage side switching elements are closed at least once in the four combinations.
