In this paper, we investigate the transitional dynamics and quasi-periodic solution appearing after the Saddle-Node (SN) bifurcation of a periodic solution in an inductor-coupled asymmetrical van der Pol oscillators with hard-type nonlinearity. In particular, we elucidate, by investigating global bifurcation of unstable manifold (UM) of saddles, that transitional dynamics and quasi-periodic sol...

A high step-down direct current-direct current (DC-DC) buck converter with a coupled-inductor in its topology is presented this study. The switching pattern of the proposed interleaved; therefore, voltage stress on semiconductors and components low since primary will be divided between blocking capacitors side. Thus, semiconductor elements low. As result, preselected can chosen ratings. In addi...

A loosely coupled inductive power transfer (IPT) system for industrial track applications has been researched in this paper. The IPT converter using primary Inductor-Capacitor-Inductor (LCL) network and secondary parallel-compensations is analyzed combined coil design for optimal operating efficiency. Accurate mathematical analytical model and expressions of self-inductance and mutual inductanc...

We show how to build an inductorless version of the classic Chua’s circuit. The goal is to build Chua’s circuit quickly and easily. To this end, only off-the-shelf components are used. A suitable inductor for Chua’s circuit is often hard to procure. Here, the inductor is replaced by a single op-amp synthetic inductor circuit. The synthetic inductor is novel in the sense that it is not a gyrator...

In this paper, a family of zero-voltage-transition (ZVT) magnetic coupling bidirectional DC/DC converters (BDCs) is proposed. The inductor has two functions: to serve as filter; and provide the auxiliary current. addition, phase-shifting control method used reduce conduction loss circuit. switches are all working under zero-current-switching (ZCS) conditions; thus, have no switching loss. Furth...

In this article, a three winding coupled inductor-based dual active bridge (TWCI DAB) dc-dc converter is proposed. Similar to the current-fed DAB converter, proposed TWCI has small input current ripple and wide voltage range. addition, zero-voltage switching (ZVS) of all switches in full load range under variation can be realized. With magnetic integration structure, size total magnetics reduce...
