The leakage inductance of the High Frequency Transformer(HFT) in the flyback topology can be used an inductor of the Low Pass Filter(LPF) to reduce ripple and ripple noise in the output voltage. But, the values of leakage inductance and magnetizing inductance in the HFT are within ±20[%] And the operating temperature of the HFT increased by the leakage inductance Therefore, the leakage inductance of the HFT in the flyback topology has minimum and the LPF has non-polarity ceramic capacitor in the output stage. In this paper, the LPF in the flyback topology takes PCB capacitor using double layer of PCB without non-polarity ceramic capacitor Its experimental results show the reduced ripple noise and the reduced ripple in the output stage
