摘要： A grain-oriented silicon steel with low iron loss, wherein the silicon steel is provided with a plurality of grooves on its surface, each of the grooves is 10-60 µm in width and 5-40 µm in depth, and the spacing between adjacent grooves is 1-10 mm. The manufacturing method therefor comprises: scoring the surface of the grain-oriented silicon steel with low iron loss by using a laser in order to form the grooves. The grain-oriented silicon steel with low iron loss can maintain the magnetic domain refining effect in a stress-relief annealing process, and avoid the introduction of more residual stress.

摘要： A magnetoelectric device includes at least one reluctance component (2), at least one damping capacitor (C d ), and a switching circuit (S1, S2). The reluctance component (2) includes a capacitive and inductive magnetic core unit (21) having a loop-shaped first segment (22) and a second segment (23) connected to the first segment, and at least one coil (L) wound around and loosely coupled to the magnetic core unit (21). The damping capacitor (C d ) cooperates with the coil (L) to form a resonant circuit. The switching circuit (S1, S2) makes and breaks electrical connection between the coil and a DC power source (V dc ) so that an eddy current flowing through the resonant circuit may be generated for storing energy in the damping capacitor (C d ). The second segment (23) may be a permanent magnet. The damping capacitor outputs current to charge the DC power source (V dc ) when the voltage across the damping capacitor exceeds that of the DC power source (V dc ). In such a manner, magnetic energy of the magnetic core unit that has positive magnetic damping effect is converted into electrical energy for output, such that output electrical energy is increased, thus promoting usable electrical energy stored in the DC power source (V dc ).
摘要翻译：磁电装置包括至少一个磁阻分量（2），至少一个阻尼电容器（C d）和开关电路（S1，S2）。磁阻分量（2）包括具有环形第一段（22）和连接到第一段的第二段（23）的电容和感应磁芯单元（21），以及缠绕在其上的至少一个线圈并松动地联接到磁芯单元（21）。阻尼电容器（C d）与线圈（L）配合形成谐振电路。开关电路（S1，S2）使线圈和直流电源（V dc）之间的电连接断开，从而可以产生流过谐振电路的涡电流，用于在阻尼电容器（C d）中存储能量。第二段（23）可以是永磁体。当阻尼电容两端的电压超过直流电源的电压（V dc）时，阻尼电容器输出电流来对直流电源（V dc）充电。以这种方式，具有正磁阻尼效应的磁芯单元的磁能被转换为用于输出的电能，使得输出电能增加，从而促进存储在直流电源（V dc）中的可用电能。
