Hi Lisa, I can't check your project at present as I won't have access to a PC for a couple of days (EasyEDA really isn't suited to smartphones...). Can you wait that long? A few pointers in the meanwhile... There's a lot of useful information from: http://www.compliance-club.com/ including a series of articles about end design for PSUs etc. You have to register but it's free (at least it is from the UK). This chap, Keith Armstrong, of Cherry Clough consultants is the author and also publishes articles with free registration from their site. http://www.compliance-club.com/default.aspx?id=19 http://www.cherryclough.com/home This is one of his with some handy references: https://www.google.com/url?sa=t&source=web&rct=j&url=http://www.interferencetechnology.com/wp-content/uploads/2012/04/Armstrong_DDG12.pdf&ved=2ahUKEwix8OvMpavZAhWpi1QKHfgFCIEQFjADegQICRAB&usg=AOvVaw2fWraM-xeCYvfCAz1D8nTE (Sorry about the horrid Google link). Sorry but I can't find d the exact article I'm thinking of right now.

OK, try searching for: `keith Armstrong power supply input filter` Or: `keith Armstrong emc design techniques` It's the Design Techniques series of articles (8 or more of them) that you need to look for. You can probably work backwards from the URL of one of the archived articles to reach the rest.

Andy, Yes I can wait the 3 days, but will check out your references. I will look at them, and also I have much to do with the circuit area after Rectification and Regulation down to 12Vdc. I even looked at a couple of P.S. boards from tv's I have around my lab, they are both 2 layer though, with some shielding. Thanks, -Lisa

These are the (6) articles... http://www.compliance-club.com/archive/keitharmstrong/design_techniques1.html through to: http://www.compliance-club.com/archive/keitharmstrong/design_techniques6.html

Hi Lisa, Just shared some ideas with you. :)

You might find these useful if you need to discharge your X capacitors across your AC input supply to meet safety and low standby power regulations: https://www.nxp.com/products/power-management/ac-to-dc-solutions/ac-dc-controllers/greenchip-x-capacitor-discharge-ic:TEA1708T https://ac-dc.power.com/products/capzero-family/capzero-2/ http://www.monolithicpower.com/Products/Product-Detail/56/AC-DCPowerConversion/PowerSavers/HF81

Andy, Thank you very much for the information. The MPS HF81 is just the ticket to take care of the X-Cap discharging, with both safety and low power draw,and minimal components/ price. In the past we have generally used a bleeder resistor, or a much more complicated solution with discrete components. In this case both Craig and I missed the discharge portion completely. Thanks again for the ideas. -Lisa D

Hi Lisa, Did you find the other schematics I shared OK? I wasn't sure if I got the right user details.

Hi Andy, Yes I believe we got all the info sent. Also now that I have a decent handle on using the EasyEDA System, I have volunteered to be part of the Beta Software Test. The timing is right, as after the Power Supply board is ordered, I have to start on the Micro-Processor control board schematic and board layout. Thank You for all the information and help. -Lisa D.
