Summary:PROBLEM TO BE SOLVED: To provide a motor controller in which loss of an inverter circuit can be reduced efficiently not only in a light load region but over a wide range. SOLUTION: In the multiple inverter motor controller for driving or regenerating a motor M by a first inverter 3 consisting of high potential side transistors 8a and 8b and low potential side transistors 9a and 9b of different characteristics, and a second inverter 4, switching between the first inverter 3 and the second inverter 4 is controlled based on the requested operational condition of the motor M.
