POWER CONVERTER, LOADING DEVICE, AND CONTROL METHOD

摘要

PROBLEM TO BE SOLVED: To securely prevent single operation of a distributed power source.SOLUTION: A power converter Y includes: a power conversion part Y11 that converts alternating-current power to direct-current power; and a frequency shift promotion part Y13 that feedback controls an operation frequency of the power conversion part Y11 to a direction promoting a wavelength shift by detecting a system frequency or a deviation of the system frequency.
