According to one embodiment, an inverter controller includes a current controller which calculates and output PWM modulation ratio instructions of a first phase and a second phase, such that an inverter outputs a predetermined current; a switching timing arithmetic unit which calculates timings at which switches of the respective phases are opened and closed; a simultaneous switching avoiding unit which determines whether a first switching timing for changing over the switch of the first phase and a second switching timing for changing over the switch of the second phase coincide or not, and to generate, upon determining that the first switching timing and the second switching timing coincide, triangular-wave carriers of the first phase and the second phase by making different waveforms of the triangular-wave carriers; and a switch opening/closing timing generator which calculates a timing for opening/closing the switch.
