----------------------------------------------------------***-------------------------------------------------------The solar cell produced the direct electricity Abstract This project deals with high step-up high efficiency dc-dc from sun light which can used power equipment or converter for photovoltaic energy conversion. The proposed recharge battery. Nowadays the majority photovoltaic converter employs a coupled inductor and two voltage modules are used in grade connected power multiplier cells to achieve high step-up voltage gain. The generation. The photovoltaic power generation operating principle and the steady-state analyses of voltage gain are described in detail. Comparing the results of C filter employs number of solar cell contain photovoltaic and PI filter is used to reduce the harmonics. Obtaining output material. The power produced from the PV panel based voltage 400 V for 20-30 V input via MATLAB simulation. The on the size of the panel. If we required more power, the maximum efficiency of the prototype is nearly 97.7% and the efficiency is higher than 97% over a wide load range. size of panel will panel will increased. So reduced the size of the panel we are using integrated high step-up Key Words: Coupled inductor, C filter, PI filter, voltage converter. In this integrated high step-up converter multiplier cells, high step-up voltage gain and maximum will have coupled inductor, voltage multiplier circuit. In efficiency, MATLAB simulation. this coupled inductor and voltage multiplier circuit will 1. INTRODUCTION boost the power produced by the panel. This power dc so we need to convert this power to dc. To reduce the The previous method of photovoltaic system harmonics we are using the C filter and PI filter .so this with module integrated converter is only used in system will used for both ac and dc power applications. medium and low power applications. In this method five operating modes in one switching period of the the string with centralized converter improved energy, proposed converter. Figure 1 shows the circuit diagram low installation cost. The drawback of this method is it of proposed converter and Figure 3 and 4 presents the cannot be used for high power applications and it operation modes, briefly described as follows cannot be used for ac power application. Nowadays the power requirement is very high. So now we are get the 2. CIRCUIT DIAGRAM power from the different power plants. His power The high efficiency coupled inductor integrated plants are using the coal, uranium as fuel. but these dc-dc boost converter is shown in figure 1.It works in fuels are not renewable source and it pollute the continues conduction mode and discontinues atmosphere also .so In focusing future the power are conduction mode. The following conditions are produced by renewable source only and maximum assumed to simplify the circuit analysis: all the amount of energy produced by sunlight. The power capacitors are large enough that their voltage can be produced by this is only by photovoltaic effect. The considered constant in one switching period; the photovoltaic effect is first observed by Alexander power devices are ideal; the leakage inductance of the Edmond at 1839. The photovoltaic effect refers coupled inductor is small; and n = N2/N1. photons of light existing electrons into higher state of energy, allowing them is act as charge carriers for an electric current.
