Switching Power Supplies
In the switching power supplies of devices such as computers, servers, and communication base stations, nanocrystalline cores can be used to make high-frequency transformers and inductors. It can effectively reduce core losses, improve power conversion efficiency, enable the switching power supply to remain stable under high-frequency operating conditions, reduce the size and weight of the power supply, and at the same time, reduce heat generation and enhance power supply reliability.
Inverters
In the inverters of photovoltaic power generation systems, new energy vehicle charging facilities, etc., nanocrystalline cores help achieve efficient DC - AC conversion. Its high magnetic permeability characteristic can reduce the excitation current and cut down on reactive power losses; the low-loss characteristic can improve the overall efficiency of the inverter and reduce energy waste.
On-Board Chargers (OBC)
The application of nanocrystalline cores in on-board chargers can improve charging efficiency and shorten charging time. Within the limited space inside the vehicle, by taking advantage of its small size and high power density, it meets the vehicle's requirements for the miniaturization and high performance of the on-board charger.
