Advantages of Planar Transformers

a. Structure: very simple, by vertically wound copper coils or stamped copper sheets, three-layers insulated wire coils and ferrite cores, compact, sturdy, high reliability, high stability, high consistency, and easy to manufacture;

b. Electrical performance: with low magnetic leakage, good resistance to electromagnetic interference, high efficiency, low temperature rise, high current, strong overload capacity, and high insulation strength;

c. Dimension: small size, light weight and flat, can be directly inserted into PCB for easy installation;

d. Usage: widely used in new energy industries such as charging pile, photovoltaic inverters, energy storage inverters, vehicle OBCs, and digital power amplifiers etc.
