Title:
POWER CONVERSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/116437
Kind Code:
A1
Abstract:
This power conversion device is equipped with: a reactor in which a direct current winding and a plurality of coupled windings are wound around a single magnetic body, one end of the direct current winding is connected to a voltage source, one end of each of the coupled windings is connected to the other end of the direct current winding, the other ends of the coupled windings are connected to intermediate connection points of a plurality of upper and lower arms comprising switching elements, and the magnetic flux generated by the current flowing through the direct current winding and the coupled windings converges in the same direction; and a control device for controlling the switching elements. Therein, the upper arm or lower arm is controlled by in-phase driving or interleave driving, on the basis of the duty of the switching operation.
