In this paper, a new method is presented for mathematical modeling of the buck-boost dc-dc converter in continuous conduction mode (CCM). The proposed method consists of two stages. At first stage, the related relations of the inductor current and the output voltage are obtained using the Laplace transform. In the second stage, the initial values of the inductor current and the output voltage are...
In this paper, the stability of the boost dc-dc converter in the continuous conduction mode (CCM) is investigated by using a new modeling method. The proposed method is based on the two Laplace and Z transforms. The Laplace transform is used for determination of the general relations of the inductor current and the output voltage. Also the Z transform is used for obtaining the transfer function of...
Since magnetic core of an inductor is easily saturated and then absorbs extra energy due to saturation, most of inductors are designed with an air core. The inductor requires so many wires to make large inductance and these expensive coils are one of the weak points of the dc reactor type fault current limiter (FCL). To solve this problem, reverse magnetization bias method is introduced. One kind...
