Title: Power conversion device
Inventor: TOI Takato
IPC: H02M3/28
Filed: 2021-07-28
Abstract: To suppress DC bias magnetism of an inductance element with a simple and low-cost configuration in a DAB type power conversion device.SOLUTION: By sampling an output signal of a current detector at a sampling period, detection values of a primary side AC current IL1 and a secondary side AC current IL2 are acquired. Using the detection values of the AC currents IL1, IL2, a DC component included in an AC current running through an inductance element is computed. On the basis of the computed DC component, a primary duty command value for controlling a primary bridge circuit and a secondary duty command value for controlling a secondary bridge circuit are formed. According to a phase difference command value, the primary duty command value and the secondary duty command value, switching operations of the primary bridge circuit and the secondary bridge circuit are controlled. The sampling period is set to be longer than the switching period of a semiconductor switching element in the switching operation.SELECTED DRAWING: Figure 11

Title: Recycled fiber and its manufacturing method
Inventor: GODA HAYATO
IPC: D06M11/74
Filed: 2021-08-24
Abstract: To provide recycled fibers and its manufacturing method in order to overcome difficulty such that fibers for recycled reinforced plastic (glass fiber, aramid fiber, carbon fiber, basalt fiber, etc.) are usually obtained by pulverizing the reinforced plastic and burning a matrix resin component of the pulverized product at high temperature to separate it, through this process, virgin fibers are coated with a sizing agent and oxidized on a surface in order to improve adhesion with the resin, but a surface structure changes significantly due to this burning process, in addition, due to the presence of impurities that cannot be removed in a refining process, surface properties are different from the virgin fibers, so problems such as poor adhesion to resins are likely to occur, and makes reuse difficult.SOLUTION: By attaching graphene oxide to a surface of a recycled fiber, the recycled fiber can have an excellent performance as a fiber-reinforced plastic. By mixing a graphene oxide dispersion and recycled fiber dispersion, the recycled fiber having the graphene oxide attached to the fiber surface can be obtained.SELECTED DRAWING: None
