In close loop converter process the output voltage is compared a set voltage and the error is decreased by controlling the switching pulse. The output voltage is decided by the switching frequency and duty cycle. Open loop converter – Boost converter said to be a open loop converter when there is no feedback between input and output, therefore the open loop converter cannot be regulated.Ĭlosed loop converter – Boost converter is said to be a close loop converter when there is feedback between input and output, therefore the close loop converter can be regulated.Ĭontrol of close Boost Converter is utilized to acquire a steady DC output voltage. The boost converter can be structured in two different ways. The large time constant compared to switching period represents that a constant output voltage Vo(t) = Vo(constant) The capacitor used at the output side of the circuit considered as large enough that the time constant of RC circuit in the output stage is high. Working principal of boost converter is based on inductor used at input side of circuit is generally use to make barrier for sudden varying of input current ,it stores the energy in form of magnetic energy when the switch is in off condition and gets discharge when switch is closed. Principle of operation of Boost converter Vout>Vin, therefore input current will be more than output current. Input power (Pinput) = output power (Poutput)Īs we know that the output voltage is greater than input voltage
