Title:
電力変換装置
Document Type and Number:
Japanese Patent JP6380156
Kind Code:
B2
Abstract:
A power converter a controller that includes an instruction calculator calculating a first voltage instruction value that is applied to a first winding group, for example. An application voltage to the first winding group is controlled, for example, in a first period so that a first neutral point voltage shifts below a center-of-output value of an outputtable range is outputted, and a second neutral point voltage shifts above the center-of-output value of the outputtable range. The instruction calculator calculates the first instruction value for enabling a switching between the periods, after a lapse of a switch period that is variably calculated based on a preset physical quantity. In such manner, a ripple of a torque or an electric current accompanying the switching between the periods is reduced.
