Webcost isolated flyback converter with the TL494. Component selection and magnetics design is also shown. Before current mode control was successfully implemented, the TL494 PWM mode ensured low EMI and noise operation due to its trailing edge modulation technique. The power supply is designed for +5-, +15-, WebMay 15, 2024 · Vo is the output voltage. (5V in my example) n is probably the turn ratio. (10:1) The voltage across the transformer is 50V on the primary and 5V on the secondary. (when the MOSFET is off and the diode is on) Using my numbers, the voltage at point where transformer and LLK connect is 50V above Vin. Vsn must be the voltage across the …
