Hi everyone,
We are developing a Smart Device that is classified for Class III Immunity and Emissions CLASS B (CE).
We begin testing a Chinese power supply called "wx dc12003" switch mode power supply. We did Conductive Emission tests and failed of course. Also, the surge test fried our cheap power supply.
Now we are thinking to add external circuits to increase the performance and maybe pass the tests.
What do you think, can it be solved with these external circuits that I've attached below, or what other proposal do you have. Thanks.
