How to select or design the magnetic core of 1kw-2kw high-frequency transformer

 

High frequency chain inverter technology USES high frequency transformer to replace the bulky power frequency transformer in the traditional inverter, which greatly reduces the volume and weight of the inverter. In the hardware circuit design of high frequency chain, high frequency transformer is an important link.

 

The design of high-frequency transformers should start with the magnetic core. Switching power transformer magnetic core is mostly used in the low magnetic field of soft magnetic materials, it has a high permeability, low coercivity, high resistivity. High permeability, in a certain number of coil turns, through a small excitation current can withstand a higher voltage, therefore, in the output of a certain power requirements, can reduce the magnetic core volume. The magnetic core has low coercivity, small hysteresis area and low iron consumption. High resistivity, low eddy current, low iron consumption. Ferrite material is composite oxide sintered body, with high resistivity, suitable for high frequency use, but Bs value is relatively small, often used in switching power supply.

 

High frequency transformer design usually adopts two methods [3] : the first is to first find out the core window area AW and magnetic core effective cross-sectional area Ae product AP (AP=AW * Ae, called core area product), according to the value of AP, check the table to find the required magnetic material number; The second is to first find out the geometric parameters, look up the table to find out the magnetic core number, and then design.
