EFFICIENT PHOTOVOLTAIC POWER SUPPLY VOLTAGE REGULATOR

摘要

Invention herewith described refers to the process of making a photovoltaic power supply voltage regulator with higher efficiency ratio than the existing ones.The existing photovoltaic power supply voltage regulators and battery charge through the photovoltaic module regulators use the average point of the natural U/I curve of the photovoltaic modules and voltage characteristics of batteries. Recharging batteries is firstly performed with constant voltage with a maximum current that the photovoltaic modules can provide, but after achieving the maximum charging voltage the current drops to lower values. In the process, the stationary operating point of photovoltaic PV modules is used, which is below the maximum value of the efficiency ratio. The efficient photovoltaic power supply voltage regulator uses the working principle of dc voltage regulator (chopper) and recharges the battery on the same principle as the battery charging the conventional regulator but with the current that is about 20 per cent or more higher than the current obtained by battery charging the conventional regulator.This device should be used on the same points of applications as the conventional charging regulators and thus with the same conditions of application, the accumulated power will be increased for 20 percent or more.This electronic device is of simple design and the quality is achieved by selecting the components of the appropriate quality.
