Abstract
In a calculation method of calculating a switching wave form of an inverter by expressing a wave form obtained by measurement or simulation using a function formula, an intermediate terminal is provided between an upper terminal and a lower terminal of an inverter arm and a power supply of a voltage function formula is provided between the upper terminal and the intermediate terminal or the intermediate terminal and the lower terminal. Further, it may be configured such that a variation impact from peripheral circuits at time of switching is calculated and voltage correction calculation is performed to prevent the calculated switching wave form from changing due to the calculation of the variation impact.
