“…CDR is widely used in applications with low-output voltage and high-output current because the root-mean-square (RMS) current on the transformer secondary is small and the output voltage ripple is reduced [18]- [20]. Many previous studies have reported on the general advantages of CDR-based topologies [21]- [25].…”

This study examines the zero-voltage switching (ZVS) operation of an active-clamped forward converter (ACFC) with a current-doubler rectifier (CDR). The ZVS condition can be obtained with a much smaller leakage inductance compared to that of a conventional ACFC. Due to the significantly reduced leakage inductance, the design is optimized and the circulating loss is reduced. The operation of the ACFC with a CDR is analyzed, and a detailed ZVS analysis is conducted on the basis of a steady-state analysis. From the results, a design consideration for ZVS improvement is presented. Loss analyses of the converters shows that enhanced soft-switching contributes to an efficiency improvement under light-load condition. Experimental results from a 100-W (5-V/20-A) prototype verify that the ACFC with a CDR can attain ZVS across an extended load range of loads and achieve a higher efficiency than conventional ACFCs.

“…2 gives four typical candidates [9][10][11][12] for PSFB part. PSFB-1 is the conventional PSFB structure [9]; PSFB-2 shows the primary-side energy stored inductor structure [10]; PSFB-3shows the currentdoubler-type rectifier structure [11] and PSFB-4 shows the voltage-doubler-type rectifier structure [12]. It's emphasized that, since the ZVS of the lagging leg can be achieved with the help of the HB branch later, the bulky auxiliary components for ZVS can be removed, the PSFB parts thus become more compact and their performances are also improved.…”

This paper focuses on a new dc-dc family, in which the lagging leg of a phase-shifted full bridge (PSFB) converter is also used to structure a new half bridge (HB) branch. Such a shared-lagging-leg (SLL) concept not only extends the ZVS range of lagging leg, but also provides another energy path for possible function extension, such as efficiency improvement and dynamical enhancement. In this paper, the existent SLL converters are reviewed and the general derivation of the SLL family is given, the ZVS feature in the SLL is analyzed and the possible improvements are presented. Finally, a new SLL converter integrating a current-driven PSFB and a LC resonant half bridge structures are proposed. The proposed SLL converter preserves all the advantages of its PSFB and HB counterparts, but eliminates their drawbacks, i.e., it has the minimal component amount, achieves the full ZVS range in the legs, eliminates the circle current and gets fully regulation in the output. The aforementioned analysis and design are also verified by the experimental results.

“…4, the test bed consists of a recycling, which receives output power from the LDC and converts it to input power, and an isolated circuit stage, which compensates for the losses of LDC. The power loss of the TS-Boost converter becomes the output load capacity of the TT-Forward converter, and the entire power requirement is the sum of the power loss in the TS-Boost converter and the power loss in TT-Forward converter [5][6][7][8][9][10].…”

-This paper reports the development of test bed with the energy recovering technique using two-step boost converter. The device is utilized for LDC aging test of Hyundai Motor's LPI AVANTE HEV in mass production. The developed power recycle type test bed is designed as 1.5 kW class to test up to the maximum load power of LDC and is also designed to supply scant power supply up to 500 W after power recycle. The theoretical design analysis and operational characteristics analysis results of test bed are reported, and its practicality and reliability are verified through the test result. Also, the finally developed test bed confirms approximately 79~85 % energy saving effect compared to the usual traditional aging test system.
