Title:
インバータ制御方法
Document Type and Number:
Japanese Patent JP6772312
Kind Code:
B2
Abstract:
There is disclosed a method for controlling an inverter in a solar pump system. The method includes; when a current DC link voltage is above or equal to a reference level, and when a previous output frequency of an alternating-current (AC) voltage applied to a load increased in a previous period, increasing an current output frequency of an AC voltage to be applied to the load at a first slope; and when the current DC link voltage is above or equal to the reference level, and when the previous output frequency of the AC voltage applied to the load decreased in the previous period, increasing the current output frequency of the AC voltage to be applied to the load at a second slope smaller than the first slope.
