I need Circuit diagram of SwitchMode adjustable Voltage Regulator
The features of the circuit should be:
- Transformer less (transformers are heavy and wastes electrical energy more (as heat)
- Should be able to take input from 220V AC and also 9V DC (Battery) (if single diagram can’t do both, 2 different diagram will also be ok)
- Voltage adjustable (30V – 6V) , little more or less is OK.
- I prefer LM317T IC (as it is easily available and I’m familiar with it)
- If Inductor is used, description of the inductor (how to make it, readymade inductor is not available in my place (Bangladesh) )
Can anyone please help me?
Note 01: I got an inductor core (like the attached pic) which has around 50 turns of wire (may be 18 / 19 Awg). Can you guess the specification of the core and how to build inductor required for the circuit.
Note 02: Does AWG of wire matters, if yes, how
