With the continuous vigorous development of the new energy industry, inverters, as important equipment for energy conversion, have a direct impact on energy efficiency, stability, and user experience. As one of the core components of the inverter, the quality and selection of magnetic core materials have a crucial impact on the overall performance of the inverter.
This article will discuss the importance of magnetic core materials for inverters，from the definition, the working process, the applications and some other relevant information for a better understanding of one of the raw materials for inverters.
What’s magnetic core materials for inverters
This year, the overall demand for magnetic materials industry has steadily increased, and the rapid development of downstream application fields such as photovoltaics storage and wind power has brought development opportunities to the magnetic materials industry. As an important component of magnetic components, the performance and quality of magnetic cores affect the energy storage, filtering, and power conversion efficiency of the final magnetic components.
The magnetic core materials of inverters is mainly used for energy storage inductors, filtering inductors, and transformers to improve energy efficiency, reduce losses, and optimize electromagnetic compatibility. If you are not familiar with the meaning of inductors, "what is an inductor" is for your reference. Common magnetic core materials include Sendust, High Flux, MPP, Nanocrystalline, and Ferrite. Different materials have their own advantages in magnetic permeability, saturation magnetic flux density, loss characteristics, and temperature stability to meet different application requirements.
The Comparison of magnetic core materials for inverters
Inverter manufacturers can optimize power conversion efficiency, reduce losses, and improve system reliability by selecting appropriate magnetic core materials based on different inverter architectures. The following is a comparison of commonly used magnetic core materials.
Ferrite
Soft ferrite is a series of composite oxide materials containing iron oxide. The characteristic of ferrite is low saturation magnetic induction intensity, but high permeability and resistivity. Its most widely used applications are high-frequency transformer cores and various inductor cores
Silicon steel
Silicon steel improves magnetic aging by adding a small amount of silicon, and is widely used in electronic devices and measuring instruments such as motors and generators. The disadvantage is that eddy current losses are relatively high at high frequencies.
Amorphous
Amorphous nanocrystals have high saturation magnetic flux density, a wide frequency range of use, good stability in AC/DC superposition, high saturation magnetic flux density, but low magnetic permeability, and are widely used in energy conversion devices. The total amount and structure of silicon steel remain tightly balanced, and amorphous alloys have broad prospects.
Magnetic powder core
Magnetic powder core is a process of making magnetic materials into powder, adding insulating material between powder particles, and compressing them into magnetic cores. It is widely used in energy conversion devices such as photovoltaic inverters and charging stations, but its disadvantage is that its magnetic permeability is relatively low.
The features of high-quality magnetic core materials
High quality magnetic core materials are crucial for the performance of inverters, determining their energy efficiency, power density, electromagnetic compatibility (EMC), thermal management, and long-term reliability. High quality inverter core materials worldwide typically possess the following characteristics to meet the demands of efficient energy conversion, low loss, and high reliability.
Low core loss
Low rail losses (low eddy current losses, low hysteresis losses) can improve the efficiency of inverters and reduce heat accumulation. Reduce heat accumulation in the inverter, improve the efficiency and operational stability of the inverter, especially under high-frequency operation, and reduce overall energy loss.
High Saturation Flux Density (Bs)
A higher saturation magnetic flux density can support higher current carrying capacity, making the magnetic core suitable for high-power density inverter applications. High Flux alloys can reach up to 1.5T, while nanocrystalline alloys can reach over 1.2T.
Excellent thermal stability
Maintain stable magnetic permeability under high temperature conditions to avoid a decrease in magnetic core characteristics with temperature changes. Inverters can maintain efficient operation in high or low temperature environments and adapt to stable performance under different climatic conditions.
Adapt to high frequency performance
Suitable for high-frequency applications ranging from tens of kHz to MHz, such as photovoltaic inverters, energy storage inverters, and UPS power supplies. Especially suitable for devices such as photovoltaic inverters and energy storage inverters that require high-frequency switching, improving the inverter frequency response capability and power conversion efficiency.
Good EMI suppression capability (Electromagnetic Interference Suppression)
Has good common mode and differential mode noise suppression capabilities, reduces electromagnetic interference, and improves power quality. Nanocrystalline materials exhibit excellent performance in EMI filtering inductors.
Excellent DC Bias Performance
Ensure that the inductance is not easily saturated under high DC current and maintain a stable inductance value. For example, iron silicon aluminum (Sendust) and high-throughput alloy (High Flux) magnetic cores have good DC bias capability.
In the context of global dual carbon, the field of new energy has experienced explosive development, and magnetic components and their upstream magnetic materials have also ushered in a period of high-speed development opportunities, while also facing unprecedented challenges.
