POWER CONVERTER CIRCUIT DEVICE HAVING A PLURALITY OF PARALLEL POWER CONVERTERS OR POWER CONVERTERS AND BALANCING INDUCTORS CONNECTED AMONG THEM

摘要

PROBLEM TO BE SOLVED: To provide a new power converter circuit device which has a plurality of power converters or power converter arms, and in which a current is distributed uniformly efficiently by a simple method. SOLUTION: A power converter circuit 1 which has a plurality of power converters 2 or power converter arms 2 is specified, and here a uniform current is distributed efficiently by a simple method. This is achieved by the balancing inductors arranged between the two adjacent power converters 2 being equipped with at least one ring core 5, and by the two adjacent power converters 2 or power converter arms 2 being arranged to draw a circle from different sides through the ring core 5 and also being collected to the common load circuit connection of all parallel power converters 2 or power converter arms 2.
