“…Many current-fed topologies have been discussed and analyzed in recent years. In [25][26][27][28], converters have hard switching and switches suffer from high voltage stress at switch turn-off. Thus, losses will increase and reduce efficiency.…”

This paper proposes a current-fed quasi-resonant converter with soft switching method. Input current ripple is reduced by employing two boost circuits at the input, which makes this converter appropriate for fuel cell application.Current stress on switches is reduced because of the resonance in switches, and also, as a result of zero voltage switching in switches, switching losses will be reduced in this proposed converter. In the output, the reverse recovery problem of diodes is alleviated by zero current switching, so there is no need for fast diodes anymore. The reduction of losses improves the efficiency, and in a wide range of load, efficiency is high. Experimental results on a 1-kW prototype are provided to validate the proposed concept.

“…In recent years, the conventional phase-shift full-bridge (PSFB) converters have been widely employed in high-power applications [1][2][3][4][5] because of their advantages of high conversion efficiency, high power density, and low electromagnetic interference (EMI). All primary switches can be turned on under ZVS using the transformer leakage inductance and switch intrinsic capacitance without any external passive components [6][7][8][9].…”

Abstract. This paper proposes a novel soft-switching dual full-bridge converter with shared lagging leg and dual outputs in series. Resonant clamp circuits are employed across the secondary rectifiers to reduce the voltage overshoots of the secondary rectifiers, as well as extinguish the primary current during the freewheeling interval. Full Zero-Voltage-Switching (ZVS) range of the lagging leg switches can be achieved based on the parallel full-bridge configuration. The dual outputs of the proposed converter are connected in series, and the whole output voltage can be regulated within the desired voltage range by the phase-shift control. Therefore, the proposed converter would be useful for high output voltage and high power applications. Steady state operation and distinctive features of the converter are explained and verified on a 1-kW hardware prototype, and experimental results validate the feasibility and performance of the proposed converter.

“…Most power factor correcting systems employ pulse width modulation Sarhangzadeh et al 2011;Yang and Lin 2011). Switch mode power conversion is one of the most elegant methods of electric power processing in today's industrial environment due to circuit simplicity, ease of control, and improved efficiency (Xie et al 2007;Lu, Cheng, and Ho 2008;Mason, Tschirhart, and Jain 2008). By soft switching, the switching frequency can be chosen much higher than the switching frequency of a hard switching converter (Liu and Ruan 2007;Chen, Ruan, and Zhang 2008;Das, Mousavi, and Moschopoulos 2010;Wu et al 2010;Wang, Chung, and Ioinovici 2011).…”

This article presents a power supply using an LCC resonant converter having power factor correction with burst mode operation. In order to improve the performance from no load to full load, a microcontroller with an active control has been introduced. The light load efficiency is increased using burst mode operation. The proposed controller provides zero voltage switching. Mathematical analysis is done, and steady state characteristics are drawn. A simple design example is given based on the equations. The proposed converter has good efficiency with good power factor at all loading conditions. This is shown by the simulation and experimental results obtained through testing the prototype.
