高频电源变压器CMYKDS ES N DE I IGGNHIGH-FREQUENCY POWER TRANSFORMERSDesign a high-frequency power transformer based on flyback topologyDINESH KUMAREssentially, switched-mode power supplies, or SMPS, act as AC-to-DC converters. These rectify the AC input voltage (85V-265V AC) to convert it into DC. Depending upon the design considerations, these chop the rectified voltage (DC) at very high frequencies. SMPS find use in computer power supplies, TV sets, CD players, battery chargers, adaptors, etc. Their major advantages are ligher weight, smaller size, higher efficiency and lesser cost. Let’s now consider the merits of SMPS individually. Lighter weight and smaller size are due to operation at a significantly higher frequency range and use of smaller inductive elements. Rapid switching of the pow……
