---------------------------------------------------------------------***--------------------------------------------------------------------electricity,we fount that MPPT technique is most Abstract— In this project, design of MPPT charge efficient and economical to generate electricity. The Controller shows as a buck-boost converter. This buckMicrocontroller is used only for displaying the boost converter is to maintain the constant output voltage, current and power. A charge controller is voltage as well as abstracts the more additional used to regulates the charge to battery and avoiding available power from the photovoltaic module. This overcharging. system is based on constant voltage trcking method. This system consist of buck-boost converter which is BUCK CONVERTER based on TL494 IC.TL494 is fixed frequency, pulse width modulation control circuit. Also it includes ACS It is a DC-DC power converter which steps 712 current sensor, LCD display, microcontroller, down the voltage or step up the current from its MOSFET circuit, coil burner as a load. input to output. Also it is converter which DC input Voltage is greater than DC output voltage. Key Words- Photovoltaic module, buck-boost converter method, Burner coil(load),current sensor, Ferrite core transformer.
INTRODUCTION Now a day’s, most of works are depends on electricity. so, demand of electricity is increased by day to day.But cost of generating power is more. So, for that problem, we find out the solution.We have a solar energy.It is pollution free and sustainable energy.By using this solar energy we have implemented the MPPT charge controller technique. MPPT is a maximum power point tracking charge controller to track the operating point and keep the maximum power point at highest efficicency. PV module is to deliver the available power. MPPT harvested more power from PV module and store into battery. So,battery charge current will increased and then the system efficiency also improved.By generating the electricity using this technique is more helpful to reduce the power generating cost.

Fig. Buck converter circuit The buck converter is a form of DC-DC converter that can take an input from DC source as a battery and also it could be DC derived from main AC supply through the rectifier capacitor circuit[1]. The AC input supply is gives to the rectifier circuit or it can be alternate the voltage by step-down transformer. so, the DC voltage is applied to the buck converter circuit. Then, this DC voltage is converter into AC voltage by chopper or switching transistor. Again it will be reconverted into original DC voltage. Always, ISO 9001:2008 Certified Journal
