The successful development of planar magnetic core can realize planar transformer design. Since the planar transformer requires the magnetic core and windings to be planar structure, multi-layer PCB windings should be adopted.Now, many companies have developed planar transformer, Pulse, the company developed a planar magnetic components, Israel Payton Payton company has developed a Planetics planar transformer, power from 5 w to 20 kw, since 20 KHZ and 2 MHZ frequency, efficiency can reach 98%, usually is the telecommunications, electric welding machine, computers and peripherals, network, medical electronics, industrial control, security system and the choice of electronic equipment.
