PROBLEM TO BE SOLVED: To approximate an output voltage and current of a PWM power converter to the sine wave for much contribution to elimination of torque ripple in load and fluctuation in rotation. SOLUTION: In this method of generating the PWM pulse, a plurality of output voltage commands (hereinafter, referred to as the reference voltage commands) calculated in a constant period with an arithmetic means are interpolated with a plurality of output voltage commands (hereinafter, referred to as the interpolation voltage commands), and these interpolation voltage commands are compared with the carrier to generate PWM pulse. The reference voltage command calculated previously with the arithmetic means is approximated with the linear approximation method to generate a plurality of interpolation voltage commands. |
