Description

Manganese-zinc ferrite with wide temperature range, low power consumption and high direct current superposition characteristic and preparation method thereof
Technical Field
The invention relates to the field of manganese-zinc ferrite materials, in particular to a manganese-zinc ferrite material with wide temperature range, low power consumption and high direct current superposition characteristics and a preparation method thereof.
Background
With the continuous development of electronic transformers, the requirements of light weight, high efficiency and energy conservation of the electronic transformers are becoming more and more obvious. The existing soft magnetic ferrite material is suitable for general switching power supply transformers and LCD backlight power supply current converters, is more particularly used for automobile electronics, but has a direct current Bias (DC-Bias) state when being used in most circuits such as AC-DC, DC-DC converters, inductance transformers and the like. As manufacturers for producing and processing manganese-zinc ferrite cores, higher requirements are put forward, and the direct current superposition characteristics of the cores are required to be improved. However, the power consumption of the original manganese-zinc ferrite with high direct current dropping characteristic meets the requirements at low temperature, the power consumption is obviously improved at high temperature, the power consumption at working temperature is increased, the temperature of equipment is overhigh, the energy consumption is overlarge, the requirement of energy saving is not met, and the service life of the equipment is shortened.
