LP CORES
Introduce of LP cores
LP core, EQ cores, EQ13 core, is all E-E core shapes with large wide windows, and is New planar cores. The
shape of the core is not a significant consideration for continuous mode operation due to low AC losses. For
discontinuous mode operation, the winding area window is chosen as wide as possible to minimize AC winding
losses. A table of suitable LP cores types for various power levels like ST core, SQ core, EQ13 core, LP kern,
LP22, LP23, LP32, EPX cores, EOP core, EIR core, are given for applications with the converter cores, controller
(frequency range 100kHz to 500kHz).
Application of LP cores
LP cores are widely application in Driver transformer, Wideband transformer, Transformatoren kern, DC
converter core.
