applications where power regeneration is not necessary. In that case three thyristors of the top group or the bottom group of a three phase fully controlled converter can be replaced by three diodes. The resulting converter is called a three phase half controlled converter. Replacing three thyristors by three diodes reduces circuit complexity but at the same time prevents negative

Research about LM317 Positive Adjustable Linear Voltage Regulator: The LM317T is a 3-terminal integrated circuit which can supply a load current of up to 1.5 Amps with an output voltage of between 1.2V and 37 Volts. It accepts an input voltage of between 3 and 40 volts. It can be used to regulate either current or voltage in situations where a fixed current or fixed voltage is required. The level of current or voltage required can be adjusted by connecting the chip in series with a fixed resistor

CHAPTER - 1 INTRODUCTION 1.1 STATE OF ART Photovoltaic (PV) generation is becoming increasingly important as a renewable source since it offers many advantages such as incurring no fuel costs‚ not being polluting‚ requiring little maintenance and emitting no noise among others. But still‚ these modules have relatively low conversion efficiency due to their nonlinear and temperature-dependent voltage-current and voltage power characteristics. Power generated by PV generators and injected into the
