Hi everyone,

I need advice to design a filter for uC supply 220Vca to 15Vdc -1A
It is running in a noisy environment and from time to time I found the uC hanged.
By now it is just a transformed+full bridge diode+ cap filtering.

Should I connect the (-) to earth ? Now is isolated.
Should I use a filter like used in PC power supply input ? (common+diff I think)

Any ideas and design-manufacturing tips welcome!

Thanks in advance!
MArtin

How about the voltage regulators LM78XX?! there is a LM7815, so that gives you a 15V output?
