Converter controlled solar power supply system for battery based loads
A high efficiency solar power system combining photovoltaic sources of power ( 1 ) can be converted by a base phase DC-DC photovoltaic converter ( 6 ) and an altered phase DC-DC photovoltaic converter ( 8 ) that have outputs combined through low energy storage combiner circuitry ( 9 ). The converters can be synchronously controlled through a synchronous phase control ( 11 ) that synchronously operates switches to provide a conversion combined photovoltaic DC output ( 10 ). Converters can be provided for individual source conversion or phased operational modes, the latter presenting a combined low photovoltaic energy storage DC-DC photovoltaic converter ( 15 ) at string or individual panel levels.
