In the traditional design, when high-current heat energy is lost, the performance of an electronic circuit is influenced by the heat energy loss of a coil; the heat energy loss is generated because when the high-current product works at full load, the coil has heat formed by direct-current impedance loss generated by the current passing through the copper wire and the lead wire under the influence of magnetomotive force; (the passage of current through a conductor generates heat, which is the thermal effect of the current, thus creating a thermal energy loss to the product) the heat generated by the current is typically related to the magnitude of the current, the resistance of the conductor, the time of energization; considering heat energy loss, the current industry is generally biased to adopt iron cores with smaller number of turns and larger cross section area, and the like to control the heat energy loss with lower value.
