Kā aprēķināt Transformer
Kas ir Transformer?
Calculates transformer voltage and current relationships for different turns ratios. Essential for voltage conversion and impedance matching.
Formula
Turns ratio = secondary turns ÷ primary turns
Soli pa solim ceļvedis
- 1Turns ratio = secondary turns ÷ primary turns
- 2Secondary voltage = primary × turns ratio
- 3Secondary current = primary ÷ turns ratio
- 4Power in ≈ power out (ideal)
- 5Account for losses (92-98% efficiency)
Worked Examples
Ievade
Vp=120V, Ns/Np=1/10
Rezultāts
Vs=12V
Common Mistakes to Avoid
- ✕Not accounting for transformer losses
- ✕Assuming ideal 100% efficiency
Frequently Asked Questions
What's step-up vs. step-down transformer?
Step-up increases voltage, decreases current; step-down does opposite.
Why use transformers?
Voltage conversion, impedance matching, isolation, and distribution efficiency.
