“…To solve this problem, several zero-voltage switching (ZVS) and zerocurrent switching (ZCS) techniques are reported in the literature. (8)(9)(10)(11)(12)(13) The use of the boost converter with ZVS and ZCS techniques will result in the absence of voltage and current across the power switch at turn-on and turn-off transitions, as illustrated in Figs. 4 and 5.…”

In this paper, a boost converter with a transformer capacitor cell for implementing features of double-output sources and zero-voltage switching (ZVS)/zero-current switching (ZCS) is proposed. The proposed boost converter has the following advantages: (1) By incoporating a transformer capacitor cell, the main switch can achieve ZVS and the auxiliary switch can achieve ZCS under turn-on transitions, reducing switching losses and electromagnetic interference (EMI). Therefore, the conversion efficiency and power quality of the proposed boost converter can be increased. (2) By applying the turn ratio of the transformer, the proposed boost converter can obtain double-output sources with step-up and step-down voltage functions. (3) The leakage energy of the transformer can be recovered using a capacitor, and then the energy of the capacitor can limit the reverse recovery current of power diodes, reducing reverse recovery losses. Finally, a boost converter prototype with a transformer capacitor cell for implementing the features of ZVS/ZCS and double-output sources is built. The performance and feasibility of the proposed boost converter have been verified from the simulated and experimental results.

Abstract:In this paper, a soft-switching single-ended-primary-inductance converter (SEPIC) with multi-output sources is proposed. The proposed SEPIC has the following advantages: (1) The conversion efficiency can be increased. To incorporate a soft-switching cell with a flyback-type, the power switches can achieve zero-voltage-switching (ZVS) and zero-current-switching (ZCS) features under turn-on transitions, resulting in reducing the switching losses and electromagnetic interference (EMI); (2) The applicability can be maximized. To apply the voltage ratio of the transformers, the proposed SEPIC has multi-output sources with step-up/down voltage functions. Finally, a prototype of the soft-switching SEPIC with multi-output sources is built and implemented. Simulated and experimental results are presented to verify the performance and the feasibility of the proposed soft-switching SEPIC with multi-output sources.

“…It is a very difficult task to control PMSM because PMSM is nonlinear system, multivariable and strongly coupled system. With development of modern nonlinear theories, many chaos control methods are researched (Nakashima et al, 2014;Chen and Dong, 1998;Adhikari et al, 2016). Some methods also are used to control chaotic PMSM (Wang, 2003;Kar and Mishra, 2012;Chen, 2006;Ren and Liu, 2014;Zribi et al, 2015;Jogendra et al, 2013;Freitas et al, 2016;Chen et al, 2013;Kraḧenbuḧl et al, 2011), such as OGY method, which method need find an adjustable parameter which is very complex.…”
