Rapid grow is
occurring in power converters and inverters particularly in areas of Switched
Mode Power Supply (SMPS) systems and power electronic drivers for motors and
actuators. Although ferrite cores and soft iron powdered cores are
conventionally used for medium to high frequency (1 kHz to 10 MHz)
applications, their magnetic permeability or operating flux density is
restrictively low. These factors pose a major problem in miniaturisation and
energy efficiency of medium to high frequency devices. Strip wound cores made
from soft magnetic materials such as SiFe, NiFe, CoFe, amorphous or
nanocrystalline are increasingly used as an alternative replacement to ferrite
cores for power converter and inverter circuits to help to reduce these
problems. Also, power loss, permeability, remenance and coercivity of these
cores at magnetising frequencies starting from dc to 100 kHz are important in
the design of power conversion equipment. In this project the previous system
will be improved and low-medium-high frequency measurements will be carried out
on magnetic cores with a wide range of permeabilities and sizes.
