This study presents a pragmatic implementation of photovoltaic Uninterruptible Power Supply (UPS) using battery storage. The system incorporates a 100 W photovoltaic array, a 100 VA power conditioning unit which can operate both in charging and inverting modes and a 25-Ah battery bank. The system can provide uninterruptible power, load voltage stabilization in conditions of voltage or frequency fluctuations beyond tolerable level. The conditioner is desired to give maximum power tracking and power factor correction. A pwm-gate control utilizes multilevel form of output voltage and effectively increases the switching frequency of inverter without increasing the switching frequency of the power semiconductor switches. Simulation studies over inverter output voltage and the output on grid side have been done on MATLAB. The simulation results show that the proposed design can significantly improve power quality of photovoltaic generators. |
