Description

DC/DC converters are widely used in the various electronic devices, such as large and small computers. Since all of switching DC/DC converters utilize the magnetic energy stored in the magnetic materials, then it is essentially accompanying the iron loss. In order to reduce the iron loss, various new magnetic materials have been proposed. However, it is intrinsically difficult to remove the magnetic saturation of the magnetic materials. Sometimes, this leads to the asymmetrical magnetization, i.e. magnetically saturated operation. Particularly, transient state falls into the magnetically saturated operations. In the present paper, we carried out the numerical simulation in order to examine the basic transient characteristics of full-bridge type and fly-back type DC/DC converter taking into account the magnetic hysteresis loops.
