Hi N.Kesav,

I suggest that you check all the components in the primary side and make sure no shorted output diodes at secondary side. If you replaced the FET this means the Power IC (if have) you also need to replace and retest.

For activating N Channel mosfet. we need to give postive supply to Gate.
But in this smps mosfet gate voltage is negative ....

Using for battery charger...
Now the smps is not working...
Smps Ac input bridge rectifier IN4007 diodes.one diode got damaged..and i change it...
N CHANNEL MOSFET also changed..

But output is zero v...
I check the gate voltage of mosfet...its showing negative voltage 290v dc.

How to rectify this sir...
Pls guide me sir

Just use an equivalent DIP chip, bend the pins back so flush with IC bottom, trim to length & then mount as SMD
