The high performance manganese zinc magnetic material possesses higher magnetic permeability and excellent high frequency characteristics because of reasonable improvement of raw material formula; indexes including power consumption, Curie point, and saturation magnetic flux density are improved greatly; a preparation method and the raw materials are low in cost; the raw materials are easily available; the preparation method is simple; and relative application value and promising application prospect are achieved.

Description

technical field [0001] The invention relates to the technical field of photovoltaic power generation, in particular to a high-performance manganese-zinc magnetic material for a photovoltaic inverter and a preparation method thereof. Background technique [0002] The solar photovoltaic power generation system is composed of solar panels, charge controllers, inverters and batteries. In the solar photovoltaic power generation system, the photovoltaic inverter is the key component of the entire solar energy system and the core of the photovoltaic system. Solar energy is converted to generate electrical energy through battery panels. However, the power converted by the battery panel is direct current. To truly become the alternating current that can be used in most occasions, a special equipment-inverter is indispensable. The function of the inverter is to convert direct current into alternating current. The photovoltaic inverter is photovoltaic System core device. The improvem...
