摘要：

Flyback converter, one of the switching power supply circuit with high frequency, is widely used in low power applications due to its cost effectiveness and electrical isolation characteristics. It is known that high frequency causes switching losses and reduces the efficiency of converters especially at low power ratings. Therefore, a flyback DC-DC converter operated with variable switching frequency is studied in this study. The proposed topology is operated with lower frequencies at light load conditions compared to rated output power. The results obtained from the variable switching converter are compared with the results obtained from constant switching frequency flyback topology for the same input/output conditions. It is observed that the flyback converter operated with variable switching frequency is more efficient than the flyback converter operated with constant frequency.
