Title: | Analysis and design of a high-frequency isolated dual-transformer Dc-DC resonant converter | Authors: | Li, Y Wang, R Zhong, L Mao, L Sun, C Li, X Hu, S |
Issue Date: | Jan-2023 | Source: | Electronics (Switzerland), Jan. 2023, v. 12, no. 1, 103 | Abstract: | This paper presents the operation, analysis, design, simulation, and experimental results for a proposed Dual-Transformer DC-DC Resonant Converter (DTRC). A three-arm bridge is employed on the input side and an H-type bridge is employed on the output side of the DTRC, and the two bridges are connected with two high-frequency (HF) transformers. By optimizing the ratio k of the two HF transformers, the proposed DTRC has a lower boundary power for losing zero-voltage switching (ZVS). That means the DTRC has a wider ZVS operation range and lower switching loss when compared with a traditional soft-switching pulse width modulation (PWM) resonant converter. The operation principle, power transfer, ZVS characteristics, and design procedures are analyzed in detail. Both simulation and experimental results prove the feasibility and superiority of the proposed Dual-Transformer DC-DC Resonant Converter. | Keywords: | Backflow power minimization Dual-transformer topology Resonant DC-DC converter Zero-voltage switching (ZVS) |
