Paper Title - Current Ripple Free Module Integrated Converter With MPPT Control For PV Energy Applied In Traffic LEDS


Abstract
In this Paper a passive ripple cancelling circuit (PRRC) is proposed to eliminate the output power reduction effect of photovoltaic (PV) system caused by current ripple of the PV converters. Control method for MPPT of PV system under varying irradiation and temperature conditions. MPPT control is also integrated with the proposed module integrated converter to achieve instantaneous tracking response. In this algorithm will identify the suitable duty ratio in which DC/DC SEPIC converter should be operated to maximize the power output. The SEPIC converter has been compared with conventional boost Converter about reducing the input current ripple. To provide traffic signal with solar power, the system can only operate with LED lamps consume too much power. During daytime, the traffic lights can use voltage direct from solar panel. At the same time, the battery can be charge for using at night. Advantage of solar traffic lights is that they will continue working as their main purpose is to keep traffic flowing even during power cuts. LED lamps have further benefits of longer lifespan and backup batteries will reduce congestion caused during power outages. Keywords— Maximum power point tracking (MPPT), photovoltaic (PV) energy harvesting system, ripple canceling circuit. SEPIC converter, traffic light.
