CONVERSION SYSTEM EFFICIENCY TEST

摘要

An efficiency test comprises AC-TO-DC and DC-TO-AC converters comprises formation of a energy circulation closed loop between AC-TO-DC and DC-TO-AC converters with supply of additional energy from a supplementary power source and following measurement of circulating and additional energy. A value of constant current of the supplementary power source is measured and a value circulation constant current in a point before energy supplying.
