| Abstract(in English) | This paper presents the experimental characteristics of a quasi-resonant zero voltage soft-switching (ZVS) pulse-frequency-modulation (PFM) single-ended forward dc-dc converter under the high switching frequency condition. The soft-switching dc-dc converter treated herein attains ZVS at the active switch in the primary side without an active clamp circuit, which could be advantageous for building the cost effective circuit structure. However, elimination of active clump circuit makes the single-ended forward DC-DC converter suffer from the high voltage stress on the active switch in the primary side and diodes in the secondary rectifier. As an practical solution to this technical problem, high-voltage SiC power devices is employed to the single-ended forward DC-DC converter i this research. The converter performances including the soft-switching operations and output power regulation characteristics are demonstrated in experiments, and then the practical effectiveness of the quasi-resonant ZVS-PFM forward DC-DC converter is discussed in terms of conversion efficiency. |
