Transformer Turns Ratio Calculator
Calculate transformer turns ratio and related parameters including voltage ratio, current ratio, and impedance transformation for various transformer configurations and applications.
Transformer Turns Ratio Relationships
Turns Ratio
a = Ns/Np
Voltage Ratio
Vs/Vp = Ns/Np = a
Current Ratio
Is/Ip = Np/Ns = 1/a
Impedance Ratio
Zs/Zp = (Ns/Np)² = a²
Key Relationships:
- Voltage and turns are directly proportional
- Current is inversely proportional to turns
- Impedance is proportional to turns squared
- Power remains constant (ideal transformer)
About Transformer Turns Ratio
The turns ratio is the fundamental parameter that determines all transformer characteristics. It defines the relationship between primary and secondary voltages, currents, and impedances.
Key Relationships:
- Voltage: Directly proportional to turns ratio
- Current: Inversely proportional to turns ratio
- Impedance: Proportional to square of turns ratio
- Power: Remains constant in ideal transformer
Applications:
- Voltage level conversion
- Impedance matching
- Electrical isolation
- Current transformation
Design Considerations:
- Choose ratio based on voltage requirements
- Consider current handling capability
- Account for losses and regulation
- Ensure proper insulation for voltage levels
