What should I pay attention to when applying a transformer?
1, the rated primary current of the current transformer is generally 1.2 ~ 1.4 times the line current selection of current transformers, which is mainly to consider the line overload does not burn the current transformer and ammeter or meter and other electrical equipment. 2, the rated primary current of the current transformer can not be selected than the actual line current difference is too large, which will affect the measurement accuracy of the current transformer. 3, the transformer is in the rated secondary output load range to ensure the accuracy of the transformer. Therefore, including the secondary line load and the load of the measurement device for the actual work of the transformer load, when the actual output of the secondary transformer negative

Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET) is a field-effect transistor (field-effecttransistor) that can be widely used in analog and digital circuits. MOSFET according to its "channel" polarity, can be divided into n-type and p-type MOSFET, usually also known as NMOSFET and PMOSFET, and other simple

Scientists find ordered magnetic patterns in disordered magnetic materials
A group of scientists working at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) has demonstrated that a particular property known as "chirality" - which may be used to transmit and store data in new ways - nanometer-thick samples of multilayered materials with disordered structures.

Introduction and Application of Magnetic Components
Almost all power supply circuits are inseparable from the magnetic component inductor or transformer. For example, inductors are used at the input and output to filter out harmonics of the switching waveform; in resonant converters, inductors are used to resonate with capacitors to obtain sinusoidal voltages and currents; in buffer circuits, inductors are used to limit the rate of change of the current of the power device; in boost converters, energy is stored and transferred; and sometimes inductors are used to limit the transient current of the circuit, and so on. Transformers, on the other hand, are used to electrically isolate two systems from each other, to transform voltages or impedances, or to generate phase shifts (3-phase Δ-Y transformers), to store and transfer energy (flyback transformers), and to detect voltages and currents.

New Energy Vehicles, 5G Mobile Phones The "Spring" of Third-Generation Semiconductors
From fixed-line communications and fuel cars, to 5G smart phones and new energy vehicles, power electronics has become part of our lives, and the transformation of this process can not be separated from the wide bandwidth semiconductors - third-generation semiconductors.

Use of ferrite beads in power supply systems
An effective way to filter out high-frequency power supply noise and cleanly share similar power supply rails (i.e., the analog and digital power supply rails of a mixed-signal IC) while maintaining high-frequency isolation between the shared supply rails is to use ferrite beads.
