Title:
BUSBAR STRUCTURE AND POWER CONVERSION DEVICE USING SAME
Document Type and Number:
WIPO Patent Application WO/2018/110071
Kind Code:
A1
Abstract:
This power conversion device PWCS is provided with: a smoothing capacitive element Cxp which is connected between a positive electrode terminal and a negative electrode terminal of a power supply and smoothes a change in a voltage superimposed on a direct current voltage; a switching circuit SWC which converts a direct current voltage into an alternating current voltage; a first busbar BSB1 which electrically connects the positive electrode terminal of the power supply and a terminal TCx1 of the smoothing capacitive element Cxp; a second busbar BSB2 which electrically connects the negative electrode terminal of the power supply and a terminal TCx2 of the smoothing capacitive element Cxp; and filtering capacitive elements C1, C2 which are electrically connected between the first busbar BSB1 and the second busbar BSB2. The first busbar BSB1 and the second busbar BSB2 have portions facing each other, and are disposed such that the direction of the currents flowing in the facing portions is the same.
