Six‐phase dual‐interleaved buck‐boost converter for high power‐density automotive applications
The Journal of Engineering, Volume 2019, Issue 17, Page 3592-3597, June 2019., 2019 This study presents a 30 kW, six‐phase dual‐interleaved buck‐boost converter which uses an interphase transformer together with six buck‐boost switching arms hard switched at 75 kHz for electric/hybrid vehicle applications. Parameters and construction details of the interphase transformer and common inductors are provided together with a description of

Global Dynamics of a 3 × 6 System of Difference Equations
Discrete Dynamics in Nature and Society, Volume 2019, Issue 1, 2019., 2019 In the proposed work, global dynamics of a 3 × 6 system of rational difference equations has been studied in the interior of R+3. It is proved that system has at least one and at most seven boundary equilibria and a unique +ve equilibrium under certain parametric conditions.

Discrete Dynamics in Nature and Society, Volume 2018, Issue 1, 2018., 2018 Sufficient conditions are established for the permanence in a delayed Nicholson’s blowflies model with feedback control on time scales. Our investigation confirms that the bounded feedback terms do not have any influence on the permanence of this system.

Global behavior for a fourth-order rational difference equation
, 2005 In this paper, we use a method different from the known literature to investigate the global behavior of the following fourth-order rational difference equation: xn+1=xn−1xn−2xn−3+xn−1+xn−2+xn−3+axn−1xn−2+xn−1xn−3+xn−2xn−3+1+a,n=0,1,2,…, where a∈[0 ...

Engineering Transactions, 1974 The strain bardening hypothesis assumed exerts a certain influence on the shakedown of the structure. In the present paper the problem is reduced to an analysis of the influence of the Bauschinger effect on the shakedown process.
