Hello DIY'ers, I will share the schematic and PCB layout for Fullbridge with PFC (Power Factor Correction) Switching Mode Power Supply. I will not explain in more detail this SMPS, you can immediately try this SMPS with PCB Layout below. This SMPS can be supplied with varying input voltages, ie between AC voltages between 90 - 265V, SMPS is still able to provide a stable output voltage. But also need to be considered the components used must be good, and the transformer must be in accordance with a calculation such as a schematic, how to roll the transformer must also be good and tight. Symmetrical 90V DC output voltage.
