PURPOSE:To materialize stable PWM control by lightening the adverse effect by dead time in a PWM control type of an inverter device. CONSTITUTION:A dead time correction voltage reference generator 30 generates a correction A** by correcting a voltage command value A* by the amount of the voltage reduced by dead time td. A waveform reference generator 31 generates a waveform reference A** sin (theta+90 deg.C) of 90 deg.C in phase based on the correction A**. |
