An SMPS includes a transformer.
an SPMS does include a transformer and i realised my mistake we cannot use it.
also input voltage is 24v not 230v.
i have attached a circuit is that the right one.
how do i find the value of an x rated capacitor.
This kind of circuit is deadly in amateur hands. It is NOT ISOLATED from the mains, and can kill. Hence we use transformers.
I am not sure where the question as you seem to have put the answer up your self - Switched Mode Power supply. Assuming the voltage you need is less then 230v.
If you need approximatly 230 V DC then simply rectify the mains with a bridge rectifier.
Really there is too little information here to answer the question well.
