I would like to build a toroidal transformer.
What are the formulas for dimensioning the various components?
EDIT: I try to explain myself better...
I would like to create a toroidal transformer for a power supply:
- primary: 230V @ 50Hz
- secondary: 2 x 12V
- power: 150VA
Now, for Laminated E cores transformers I have formulas for calculating the N spires needed for primary and secondary based on required input and output voltages... but for toroidal cores I didn't find any specific formula on Google and on my books...
My question is: does anyone know the specific formulas to dimension a toroidal transformer for power conversion, knowing the desired input/output voltages and output power in VA?
