The emergent induction of spiral magnets that was proposed [Jpn. J. Appl. Phys. 58, 120909 (2019)] and recently demonstrated [Nature 586, 232 (2020)] is shown to be further extended by a comprehensive treatment the Rashba spin-orbit coupling electron spin relaxation affect underlying processes spin-transfer torque spinmotive force. Within adiabatic approximation, we show output voltages are wid...

Newly developed multi-layer inductors on GaAs threedimensional MMICs are presented. We analyzed single-, double-, triple-, and quadruple-layer stacked-type inductors in what may be the first report on inductors on a GaAs MMIC with three or more layers. The performance of singleand multi-layer inductors was measured and calculated by electromagnetic field simulation. The multi-layer inductors pr...

In this paper, a novel step-up converter is proposed, which has the particular features of single semiconductor switch, ultra-high conversion ratio, galvanic isolation, and easy control. Therefore, the proposed converter is suitable for the applications of fuel-cell power system. Coupled inductors and switched capacitors are incorporated in the converter to obtain an ultra-high voltage ratio th...

An improved dual winding magnetically coupled-inductors inverter based on a Cockcroft-Walton multiplier voltage cell is proposed in this paper. Compared with the conventional generalized Z-source inverters, attains higher gain by decreasing transformer’s turns number. As result, lower cost, efficiency, larger boost factor, and density can be realized inverter. Furthermore, unlike coupled impeda...

In this paper, an improved design of a high-Q factor CMOS active inductor operating in the mid MHz frequency range is introduced. Analysis of equations has been used to gain insight into behavior of the active inductor. Moreover, based on these equations and their analysis, ways of improving quality factor are discussed. Performance improvement based on this new design coupled with use of feedb...

AbstructA novel soft-switched inverter topology is derived from the passively clamped quasi-resonant link (PCQRL) circuit. By introducing magnetic coupling between the two resonant inductors, the number of auxiliary switches can be reduced from two to one, and only a single magnetic core is required for the resonant dc link. An analysis of this novel PCQRL topology with coupled inductors is pre...
