Do you agree that the effect of leakage inductance on Duty Cyle is less prevalent in Flybacks than Forward Converters?
(ie The leakage inductance in a forward converter's transformer means the duty cycle will be increased more so than the case for a flyback)?
For example, with K factor of 0.99 in a Forward converter’s transformer, the standard Forward converter equation Vout/Vin = ND is not very accurate. (because D needs to be significantly greater than this equation predicts)
-But with a flyback with a K factor of 0.99 in its transformer, the standard flyback equation Vout/Vin = ND/(1-D) would be very accurate.
(considering CCM in all cases).
The attached simulation certainly shows this.
