Hi,
The expression for "Transfer function of a Voltage Mode Flyback power stage" is in the form of "vout(s)/vErr(s) = "
("vErr" refers to the Error voltage of the Feedback loop Error amplifier)
This is then multiplied by the "Error Amplifier and Modulator transfer function" which is in the form of "vErr(s)/vout(s) = "
However, the attached (page 467) gives the Transfer function for the TOPswitch Error Amp and Modulator in the form of "D(s)/vout(s)".
......So how can we use it to produce the overall open loop transfer function, ?...since it would need to be in the form of "vout(s)/vErr(s) = "
