METHOD AND APPARATUS FOR COMPENSATING REACTIVE POWER

摘要

An arrangement for compensating reactive power in a three phase network using two converters with the same no load d-c voltage in which the two converters are coupled in parallel on the d-c side and shorted by a common choke with the one converter operated with a delayed firing time and the other with an advanced firing time and the d-c current in the choke regulated to a constant value by influencing the firing angles of the two converters in opposite directions.
