Photo of the transformer core, where OD is the outer diameter, ID the inner diameter, and HT the height.
Photo of transformer, where P is the primary coil and A-F the 6 secondary coils.
Measured total losses against excitation frequencies at excitation current of 0.5 A; only one coil is energized at a time while others open circuited.
Measured total losses against excitation currents of 10 kHz; only one coil is energized at a time while others open circuited.
Measured B-H curves at 40 °C: maximum magnetic flux density at 1, 2, and 3 A is 0.65, 0.74, and 0.80 T, respectively.
Measured B-H curves at different temperature ranging from 40 °C to 100 °C: maximum magnetic flux density at 40 °C, 60 °C, 80 °C, and 100 °C is 0.65, 0.65, 0.64, and 0.63 T, respectively.
Measured core losses at different frequency ranging from 6 kHz to 12 kHz; experiments were carried out at 40 °C.
