“…The integrated inductors [68] can be divided into noncoupled inductors [69] and coupled inductors [70]. The integrated inverse coupled inductors can not only reduce current ripple by increasing steady state inductance, but also increase transient respond by decreasing transient inductance [41], [71]. As the interleaved phases increase, the asymmetry of the circuit as well as the complexity in design and control increase with limited benefits [72].…”

“…Particularly, the full-bridge PSM converter with a current-doubler rectifier (CDR) in Fig. 1 is a good candidate for ultracapacitor chargers due to its high power capability and soft-switching operation [7]- [9]. Power switches operate at zero-voltage switching (ZVS) conditions, reducing switching power losses.…”

“…However, the conventional full-bridge PSM converter with a CDR has several drawbacks such as high circulating currents and high output diode voltage stresses. Because of the phase-shifted switching operation between two switching legs, high circulating current flows at the primary side, causing high conduction losses [7], [8]. In addition, at the secondary side, the output diodes suffer from high voltage stresses because of the high voltage spikes at their turn-off instance [7], [9].…”

This paper proposes a high-efficiency ultracapacitor charger using a soft-switching full-bridge pulse-width modulated (PWM) converter. Conventional full-bridge phaseshift modulated (PSM) converter is used for charging ultracapacitors. However, the power efficiency of conventional converters is low because of its circulating current and high output diode voltage stresses. This study presents a highefficiency full-bridge PWM converter to overcome the drawbacks of conventional converters. The proposed converter has the advantages of lower switch voltage stresses and reduced circulating current compared to other converter topologies. The performance of the proposed converter is evaluated by experimental results for a 54-V, 35-F ultracapacitor bank. I.978-1-4799-6735-3/15/$31.00 ©2015 IEEE

“…Thus, copper loss of the isolation transformer and switch current stress are still very significant, lowering the efficiency substantially. To overcome this shortcoming, a current‐tripler rectifier [3] and coupled‐inductor current‐doubler rectifiers [4,5] have been proposed. Although all of them can reduce the peak current through the secondary winding, the current‐tripler rectifier requires triple winding at each side of the transformer, which increases design complexity and needs six active switches to control energy transformation.…”

This paper presents a current‐doubler rectifier with low output current ripple and high step‐down voltage ratio. In the proposed rectifier, two extra inductors are introduced to extend the duty ratio of the switches, which in turn reduces the peak current through the isolation transformer as well as the output current ripple; two extra diodes are used to provide discharge paths for the two extra inductors. To highlight the merits of the proposed rectifier, its performance indexes, such as voltage gain function, secondary winding peak current of the isolation transformer, and output current ripple, are analyzed and compared with the conventional current‐doubler rectifier. In this paper, a zero‐voltage‐switching phase‐shift full‐bridge converter with the proposed rectifier with an input voltage of 400 V, output voltage of 12 V, and full load power of 500 W has been implemented and verified, and experimental results have shown that 90% conversion efficiency could be achieved at full load. © 2013 Institute of Electrical Engineers of Japan.
