COMPLEX POWER CONVERTING SYSTEM FOR EDUCATION AND AN EXPERIMENT METHOD THEREOF, CAPABLE OF EXPERIMENTING COMPLEX POWER CONVERSION OF A PLURALITY OF NEW REGENERATIVE ENERGY SOURCES IN A LIMITED SPACE

摘要

PURPOSE: A complex power converting system for education and an experiment method thereof are provided to experiment a plurality of new generative energy sources regardless of an external environment.;CONSTITUTION: A power conversion and boosting unit(400) converts middle DC power into the first main AC power. The first main AC power is converted to the first main DC power. A first inverter(300) inverts the middle DC power into a second main AC power. A second inverter(500) inverts the first main DC power into the third main AC power. If the commercial power is off or lower than a reference DC voltage value, an automatic converting switch(600) automatically sets the second main AC power to preliminary power and supplies the preliminary power to the outside.;COPYRIGHT KIPO 2011
