    Hi sir.. i have found the transfer function and given the step input and got the output voltage. now how to get the power from the voltage generated since it is obtained from transfer function

    Power is calculated from either voltage and current, voltage and impedance, or current and impedance. From your question I have no clue what kind of circuit you are talking about. Please post a schematic, the transfer function, and the output voltage you "got".

    Run it through a current amplifier:

    Power = Voltage * Current.

    thanku sir..but in matlab simulink is there any single block which converts the voltage generated to power(i found the transfer function of boost converter in matlab simulink) i have generated the output voltage. now i want power from generated voltage

    IF what you are talking about is a boost converter power supply circuit, then the power depends on the load connected to the output. That is how power supplies work. If you don't understand this, then we need to back up and start with some basic electronic concepts like what are voltage and current.
