電力変換装置の制御装置
Document Type and Number:
Japanese Patent JP7100847
Kind Code:
B2
Abstract:
To suppress reduction of power factor that can occur when a three-phase single-phase matrix converter (MC) type DAB bidirectional insulated AC/DC converter is operated over a wide voltage range.SOLUTION: In a control device 4 according to the present invention is a power converter control device including a transformer 20, an AC/DC converter 30, a matrix converter 10, and a reactor L, the matrix converter 10 is configured to be controlled periodically in the first cycle so that one of a mode in which the bidirectional switch elements Sand Sare simultaneously turned on, a mode in which the bidirectional switch elements Sand Sare simultaneously turned on, and a mode in which the bidirectional switch elements Sand Sare simultaneously turned on is executed at least once in each cycle.SELECTED DRAWING: Figure 1
