Hi,
I have a project to design a high gain boost converter. I need a voltage gain of plus 20 and have decided to just keep it simple and use a cascaded boost converter. I understand a conventional boost converter can only achieve a maximum of approximately 10 which would be equivalent to a duty cycle of 90%. However I have never seen a satisfactory answer as to why 90% is considered a maximum value, would anyone be able to elaborate on this.
Many Thanks
