Regulating control circuit for photovoltaic source employing switches, energy storage, and pulse width modulation controller

摘要: A regulating circuit controls current flow from a photovoltaic power source (20) to storage battery (38) improve the conversion of solar energy electric energy. Two transistors (22, 30) are switched on and off at high frequency regulate average battery. pulse-width-modulator control chip (42) varies on-time each transistor independently provide separate voltage output voltage. The is regulated produce maximum an optimum charging available transferred battery, thereby improving efficiency system.
