PROBLEM TO BE SOLVED: To provide a power conversion device that can suppress fluctuation of a common mode voltage due to transition of an output voltage.SOLUTION: A power conversion device 1 has voltage controllers 2to 2of N, a full bridge type converter 3 having four switches QB1 to QB4, a clamp unit 4 having holding switches QC1, QC2 and a controller 5. The controller 5 controls the four switches QB1 to QB4, the holding switches QC1, QC2, and a pair of regeneration switches Q1to Q1, Q2to Q2and a pair of input switches Q3to Q3, Q4to Q4of each of the voltage controllers 2to 2of N, whereby the controller 5 switches the output voltage V1 at (2N+3) stages.SELECTED DRAWING: Figure 1 |
