SOLAR PHOTOVOLTAIC GENERATING SYSTEM USING SERIES-PARALLEL VARIABLE ARRAY

摘要

PURPOSE: A photovoltaic system using series-parallel variable arrays increases the running time of a solar system by changing the series-parallel combination of a solar module array circuit, thereby improving overall utilization. CONSTITUTION: A photovoltaic driver circuit (100) converts light energy from sun into electrical energy. The photovoltaic driver circuit includes a main array part (101), a first secondary array part (102), and a second secondary array part (103). An inverter part (300) converts the electrical energy converted into DC into AC energy and supplies it to a load (500). A detection part (400) measures solar radiation or load delivered through the inverter part. A control part (200) controls the operation of a switch included in the photovoltaic driver circuit.
