電力変換装置及び電力変換装置の制御方法
Document Type and Number:
Japanese Patent JP7351196
Kind Code:
B2
Abstract:
To provide an electric power conversion device capable of reducing an increase in manufacturing costs.SOLUTION: An electric power conversion device includes: a main circuit including first upper and lower arms, second upper and lower arms and third upper and lower arms; and a control circuit to control on-off operation of each of first to sixth switching elements by generating a pulse width modulation signal whose duty ratio of the second and lower arms is fixed to any value of 0-100%, and a pulse width modulation signal to change a duty ratio of each of the first upper and lower arms and the third upper and lower arms.SELECTED DRAWING: Figure 4
