Abstract
A power conversion apparatus connectable in parallel to a second power conversion apparatus includes circuitry that generates a carrier wave, generates a pulse signal synchronized with the carrier wave, generates power that is based on a width of the pulse signal, obtains a monitor value corresponding to a circulating current circulating between the power conversion apparatus and the second power conversion apparatus, and based on the monitor value obtained while the power conversion circuitry is generating driving power, changes a period of the carrier wave to decrease the circulating current.
