hi sir..I have modeled the boost converter as circuit modelling and found the steady state and dynamic response. now i want to replace the boost converter by single block as transfer function.
so its similar to the first order system tf=k/(1+St)
k- gain from steady state
t- time constant.
i found the gain from steady state response as 120
time constant to be 0.015s
so now my system is=120/1+S0.015
now my transfer function is vout/duty cyle=8000/s+66.66
so when is give the step input(duty cycle 0.5) my output is 60v
My clarification is the transfer function to be MISO(multi input single output), with duty cycle as one input and pv irradiation(that is boost converter input voltage) as disturbance and need to achieve the output voltage. that is finding transfer function vout/duty cyle(keeping input voltage =0) and finding vout/input voltage(keeping output voltage=0). how to do this process for boost converter with above mentioned response. please help
