How to Design a Flyback Converter in Seven Steps

WebWith a flyback converter, the output voltage (on the secondary) is referenced to ground, not the input voltage. Looking from the primary side, the voltage across the primary is equal to the output voltage divided by the turns ratio. So if the output voltage is 5V and we have a 10:1 turns ratio then the voltage across the primary is 50V.
