* Question
| What are the two effective constraints of the converter on the turns ratio? |
* Answer
| (1) The output power will be limited as the previous partial reduction.The drain of the MOSFET will see a voltage equal to the input voltage plus the output voltage multiplied by the turns ratio. The total amount of overshoot pulses will cause an increase in leakage inductance.
(2) Increasing the turns ratio will increase the peak current in the output diode, thereby reducing efficiency. |
