In this paper, an interleaved soft switching boost converter for a Photovoltaic Power Conditioning System (PV-PCS) with high efficiency is proposed. In order to raise the efficiency of the proposed converter, a 2-phase interleaved boost converter integrated with soft switching cells is used. All of the switching devices in the proposed converter achieve zero current switching (ZCS) or zero volt...

In this paper, a new type of interleaved high step-up converter including coupled inductor is proposed. The proposed has an configuration on the input side to reduce ripple current and increase power level. Moreover, stacked structure output provides input/output (I/O) voltage gain. addition, can avoid extreme duty cycle, causing larger conduction losses, by combining lossless clamp circuit wit...

Current-fed half bridge converter with bidirectional switches on ac side and a full dc of high frequency transformer is an optimal topology for single stage galvanically isolated ac-dc onboard vehicle charging application. AC are actively commutated to achieve zero current switching (ZCS) using phase shift modulation (SPSM) discontinuous (DCPSM). Furthermore, voltage turn-on (ZVS) achieved swit...

DC-DC converters are widely used in hybrid power supply systems. A buffer source of electrical energy (most often a battery bank) and its charging discharging devices integral parts such In systems where the bank voltage is less than DC-bus galvanic isolation not required, Weinberg converter as discharge device, for example, spacecraft The current trend development to increase density system. I...

We studied the DD¯⁎/D¯D⁎, D⁎D¯⁎, D¯sD⁎/D¯s⁎D, BB¯⁎/B¯B⁎ and B⁎B¯⁎ di-hadron interactions in chiral effective field theory (χEFT) up to next-to-leading (NLO) order. The above-threshold tetraquark states Zc(3900), Zc(4020), Zcs(3985), Zb(10610), Zb(10650) can be explained as corresponding resonances, respectively. also Σc(⁎)D¯(⁎) investigate three hidden-charm pentaquarks Pc(4312), Pc(4440) Pc(44...
