design buck-boost converter in simulink

[haman1986]

hi
I designed a buck-boost converter in simulink that the input voltage change between 50-200 v and output voltage is fixed in 100v
my problem now is that i cantn create a range of dc voltage that track the 50 to 200 v
i can just give only one voltage in input and have the 100 v in output
can any body help me that how can i have a changeable block that change between 50 to 200 v that i can see the output
thanks

i am n't aware of any such block in simulink..but u can do one thing..u can connect multiple dc sources(say 50) in series and connect all of them through as many switches to your network..as per your requirement u can cut the dc sources one by one or add the same one by one with always one switch conducting...
