1results about "Magnetic-bias transformers" patented technology

To provide a power conversion device capable of preventing the generation of eddy currents and improving magnetic coupling.SOLUTION: There is provided a power conversion device 100 equipped with a primary-side transformer 110 to which a primary AC voltage V1 is input from a primary-side circuit 10, and a secondary-side transformer 120 that outputs a secondary AC voltage V2 of lower voltage than the primary AC voltage V1 to a secondary-side circuit 20. The primary-side transformer 110 has a primary-side primary winding 111 to which the primary AC voltage V1 is input, and a primary-side secondary winding 112 to which power is transmitted from the primary-side primary winding 111. The secondary-side transformer 120 has a secondary-side primary winding 121 that constitutes a closed circuit 130 together with the primary-side secondary winding 112, and a secondary-side secondary winding 122 that outputs the secondary AC voltage V2 with power transmitted from the secondary-side primary winding 121. The primary circuit 10 and the closed circuit 130 are connected to a common potential.SELECTED DRAWING: Figure 1
