Scholarly Research Paper from the year 2014 in the subject Electrotechlogy, grade: 5, course: Ph.D in Power Electronics, language: English, comment: Prof. Gennady Ya. Mikhalchenko, Dr. Sc. and Dr. Sergey G. Mikhalchenko, Dr. Sc., of Tomsk University of Control Systems and Radioelectronics has been my supervisor and ass. supervisor since 2011. Prof. Gennady Ya. Mikhalchenko has published many articles in the field of SMPS and dynamics of nlinear systems well over two decades. His work is well kwn internationally. I am grateful to be working with him for my Ph.D in Dynamics of soft-switching for Power Electronics., abstract: This article propose a vel two - phase voltage boost converter (TPBC) model with soft-switching transistors, based on the use of an inductive energy storage technique in the structure of the boost voltage converter. The design proposes a mathematical and analytical model of the TPBC system using a pulse frequency width modulation (PFWM). Detailed analysis of the TPBC dynamics have been obtained, such as, stable, unstable, quasi-periodic, bifurcation phemena and chaotic regimes. Thus, reducing the issues of electromagnetic interference (EMI) and switching losses for a more energy performance and efficiency of the voltage converter which has been obtained. The TPBC has been observed to produce zero-volt-switching (ZVS) and zero-current-switching (ZCS) of the transistors transition.
