Title:
POWER CONVERSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/286197
Kind Code:
A1
Abstract:
A power conversion device (100) is provided with a converter (3), an inverter (5), and a control circuit (7) for controlling the converter and the inverter. The control circuit (7) generates a first control signal (s3) for controlling the converter (3) on the basis of a first carrier wave (Scr2), and a second control signal (s5) for controlling the inverter (5) on the basis of a second carrier wave (Scr3) which has a frequency and a phase different from that of the first carrier wave (Scr2). The frequency (fsw2) of the first carrier wave (Scr2) and the frequency (fsw3) of the second carrier wave (Scr3) have a predetermined relationship based on a current in the capacitor (4) which is connected between the converter (3) and the inverter (5).
