I need to make a transformer to step up 0.3 V to around 3 V to light LEDs . My power source is dc . This transformer has to produce a dc stepped up voltage. That is why I am using it with this circuit which I came across recently.

Can anyone please help me with the size and the frequency of the transformer. This is the rough estimate I have prepared but frequency of operation still confuses me.
frequency = 50 Hz (assumed)
N1 = 10 turns (primary)
N2 = 1000 turns (secondary)
dimensions of core = 1.5 * 1.5 sq cm
flux density for normal steel core = 1 Wb/ sq m
