<p>In accordance with variation in a DC voltage, i.e. an input voltage Vdc(t) to an inverter circuit, the duty ratio D(t) of a voltage pulse in the carrier period immediately after is modified. More specifically, processing for correcting the duty ratio D(t) is carried out for every one carrier period. Consequently, the duty ratio D(t) of the voltage pulse is corrected so that the AC waveform draws an ideal sine curve even if the input voltage Vdc(t) is varied. Thus, it is possible to obtain an AC power generator capable of supplying stable AC power.</p> |
