| Abstract |
A new material to construct a transformer is present here. This is a polymer bonded magnetic material which has a low permeability. The material has certain advantage compared with the classical magnetic materials such as power iron and ferrites because it is very easy to make and not brittle. Usually injection moulding can be used to prepare the material whereas the other material such as ferrites requires a press machine and high temperature oven. This new material has been tested against its characteristics in energy conversion, B-H curve and loss. A modelling method based on probability density function to represent alignment is used to model the core. A transformer using this material has also been made and used in a DC/DC power converter. Experiment result has shown that high efficiency can be obtained. |
