Why does the boost converter I made not produce an output voltage that matches the simulation I did?
First, this boost converter uses open-loop control.
Second, the gate driver for the MOSFET IRF540, TLP250 IGBT driver as a high side MOSFET/IGBT driver is isolated.
Third, the specifications of the ...
