What is the losses in inductor products?
In the operation of inductor products, copper losses and core losses (iron losses) are usually generated. In the circuit, due to the resistance and reluctance of the current flowing through the copper wire or magnetic core, a certain amount of electrical energy is consumed and converted into heat. Copper loss is mainly caused by the magnetic resistance generated when the current flows through the wire, and this resistance produces heat. This heat consumes electrical energy and reduces the efficiency of the circuit. Therefore, when designing a circuit, attention must be paid to the issue of copper loss and appropriate measures should be taken to reduce it, such as selecting low-resistance wires or increasing the cross-sectional area of the wire.
Core loss refers to the thermal loss caused by the current flowing through the magnetic core in the circuit. Core loss is mainly caused by the magnetic loss of the core in the magnetic field, which leads to an increase in the temperature of the core. This thermal loss consumes electrical energy and reduces the efficiency of the circuit. When designing a circuit, suitable magnetic core materials and shapes should be selected to reduce core loss and improve circuit efficiency.
Eddy current loss refers to energy loss caused by the generation of eddy currents. Eddy currents are currents generated by the electromagnetic field, and they can flow inside a conductor. When an inductor operates, the magnetic flux inside the inductor generates an electromagnetic field, which causes eddy currents to be generated. Eddy currents cause losses in the conductor and result in energy loss. Eddy current loss is a major loss in inductor products, so special techniques must be adopted to suppress the generation of eddy currents and reduce eddy current losses when designing inductor products.
