HELLO ...
Have made a voltage stabilizer using stm8s003 . one problem arises, the controller gets reset, when
1> relay operates. have used snubber, and diode across coil, but nothing seems to work.
2> when i touch mutimeter's probe at relay contact points(transformer's voltage tap).
not able to short out the problem. is there any suggestions??
Transformer is auto-type(non isolating/ common neutral)
given 1uF at Vcap.
given decoupling capacitors and electrolytic(470uF/100uF) capacitors at I/O of 7805
