Hi...
I designed a smps of 9V 3A from PI Expert tool and constructed the transformer by hand as per the spec. The SMPS is working but I am getting Spikes at output. (Image attached )
the Red line represent final voltage output and the yellow line represent the output from Transformer secondary side. The spike and ripple is increasing when I increasing the load.
Schematic pdf file :- View attachment 9V_3A.pdf
Schematic and board layout eagle files are :- View attachment schematic and layout.zip.
Also I am attaching the transformer specification View attachment transformer_construction.pdf.
Please help me to identify the issue.
Thanks and regards.
