Abstract:
A PWM controller includes a sine wave calculator to generate a sine wave signal according to a frequency command value, a first counter to generate a first triangular wave carrier signal, and a comparator to compare the sine wave signal with the first triangular wave carrier signal, generate a PWM signal, and supply the PWM signal to a power converter. The PWM controller further includes a second counter to generate a second triangular wave carrier signal that is π rad behind the first triangular wave carrier signal, a carrier number calculator to calculate a carrier number based on a multiplication number, and a carrier control unit to switch the first triangular wave carrier signal and the second triangular wave carrier signal based on the carrier number, to supply the triangular wave carrier signal to the comparator.

Claim (Index 15):
A non-transitory recording medium storing a program which, when executed by one or more processors, cause the one or more processors to perform a method comprising:\n generating a sine wave signal according to a frequency command value; generating a first triangular wave carrier signal; comparing the sine wave signal with the first triangular wave carrier signal, generating a pulse width modulation (PWM) signal, and supplying the PWM signal to a power converter; generating a second triangular wave carrier signal that is \u03c0 rad behind the first triangular wave carrier signal; calculating a carrier number based on a multiplication number, the carrier number indicating the number of carrier signals of the first triangular wave generated in a period in which a phase angle of the sine wave signal ranges from 0 to \u03c0/2 rad or from 0 to 3\u03c0/2 rad, the multiplication number indicating a ratio of a frequency of the first triangular wave carrier signal to the frequency command value; and switching a triangular wave carrier signal to the first triangular wave carrier signal or the second triangular wave carrier signal based on the carrier number, to supply the triangular wave carrier signal the comparator in a first range of the phase angle ranging from 0 to \u03c0 rad or a second range of the phase angle ranging from \u03c0 to 2\u03c0 rad.
