This is the most critical factor. It determines how many times the wire must wrap around the core for every volt of electricity.

is a constant (typically 1.1 to 1.2 for standard silicon steel). Net core area in cm2c m squared 3. Turns Per Volt (TPV) This is the most critical constant in your sheet. Formula: Bm: Flux density (usually 1.0 to 1.2 Tesla for CRGO steel). 4. Winding Calculations Calculate the actual number of turns for both coils: Primary Turns ( ): Secondary Turns ( ): transformer design calculation excel
