Dear Luqing,
Sorry that maybe it is a late notice, we have done the plug discharged test, although base on your circuit, it has a 0,1UF X2 capacitor, but the discharge voltage after 1 sec is very high, from 76 V to 117 V.
In this case, it needs to add the breeding resistor parallel to the X cap. Please study it and come back to me with the solution. Thanks.
