AC POWER GENERATING DEVICE AND STIRLING REFRIGERATING APPARATUS USING THE SAME

摘要

PPROBLEM TO BE SOLVED: To provide an AC power generating device that can feed more stable AC power. PSOLUTION: The duty ratio D(t) of a voltage pulse of a carrier cycle, immediately after the variation of a DC voltage, that is, an input voltage Vdc(t) to an inverter circuit 100 is changed, in response to the variation. In other words, processing for correcting the duty ratio D(t) is performed at each cycle of the carrier cycle. As a result of this processing, the duty ratio D(t) of the voltage pulse is corrected so that an AC waveform draws an ideal sine curve, even if the inputted DC voltage is varied.
