What does Vfh mean in the context of a transformer?

The discussion centers on understanding the meaning of "Vfh" in the context of transformers and the mathematical basis behind transformer design, specifically the relationship between turns ratio and impedance. The key formula highlighted is the turns ratio squared equals the impedance ratio (N1²/N2² = Z1/Z2). Clarifications include the determination of the primary turns (N1), which depends on application-specific factors such as peak current and core material, making it somewhat arbitrary without additional context. Examples illustrate that an 8:1 turns ratio corresponds to an 8-turn winding on the 640 Ohm side, with variations like 16 or 24 turns depending on the primary winding count. The discussion emphasizes the need for step-by-step calculation and understanding of transformer parameters to resolve confusion in applying these equations.
