Title:
POWER CONVERSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/095432
Kind Code:
A1
Abstract:
This power conversion device has an integrated magnetic component (3) formed by winding a pair of coupled windings (3a, 3b) magnetically coupled to each other and a single DC winding (3c) around one core (3d) made of a magnetic material, and the coupled windings (3a, 3b) and the DC winding (3c) have winding directions set such that DC magnetic fluxes generated by the DC currents flowing through these windings (3a to 3c) join each other in the same direction. Meanwhile, the power conversion device is provided with a bridge switching circuit (4) having four switching elements (Sa to Sd) and a control circuit (9) for controlling the switching circuit (4), wherein said control circuit (9) suppresses current ripple by switching between an interleave drive and a same phase drive in accordance with the amount of current flowing through the DC winding (3c).
