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.
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. The large time constant compared to switching period represents that a constant output. The boost converter can be structured in two different ways- 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. Closed 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.
Control of close Boost Converter is utilized to acquire a steady DC output voltage. The output voltage is decided by the switching frequency and duty cycle. In close loop converter process the output voltage is compared a set voltage and the error is decreased by controlling the switching pulse.
The fundamental activity is if the error value is certain the obligation cycle is diminished and if the error is negative the D cycle is expanded by proceeding with the procedure ceaselessly the yield voltage is looked after steady.
The output voltage of an energy component fuel cell is an element of its load. Practically speaking, a load sharing regulator can be applied on the converters, associated in equal, to accomplish a uniform load appropriation among them.
Likewise, a dq-changed two-loop current control conspire is introduced for the inverter to control the real and reactive power conveyed from the fuel power framework to the network. Design of boost converter based on maximum power point resistance for photovoltaic applications.

Tan, "Design of boost converter based on maximum power point resistance for photovoltaic applications," Solar Energy, vol. The design of the boost converter for the maximum power point tracking MPPT is complex due to the nonlinear characteristics of Photovoltaic PV modules.
In addition, PV modules are irradiance and temperature dependent, which further increases the complexity of the boost converter design. This paper proposes a new approach that eases the design of the boost converter specifically for MPPT applications. This approach represents the maximum power point of the PV module as resistance to simplify the boost converter design, which specifies the design according to the PV module parameters.
The derived equations require nine parameters to determine the inductance, input capacitance, and output capacitance of the MPPT boost converter. The results show that the simulations of the boost converter followed the desired requirements.
This proves that the calculated inductance, input capacitance, and output capacitance using the proposed method are accurate.
