PARALLEL OPERATING INVERTER WIND POWER GENERATING SYSTEM USING A CURRENT BALANCER

摘要

The present invention relate to a parallel operating inverter wind power generating system using a current balancer, the system comprising: an upper AC-DC-AC inverter and a lower AC-DC-AC inverter which are connected to a wind power generator and which are connected in parallel to each other; a current balancer connected to each of the output ends of the upper AC-DC-AC inverter and the lower AC-DC-AC inverter; and an output capacitor connected to an output end of the current balancer, wherein the current balancer is a coupled inductor in which inductors connected respectively to the output end of the upper AC-DC-AC inverter and the output end of the lower AC-DC-AC inverter are paired and coupled. According to the above-described parallel operating inverter wind power generating system of the present invention, the current ripple of an output filter inductor thereof is reduced, thus reducing the volume of the output filter inductor.
