Title:
POWER CONVERSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/082316
Kind Code:
A1
Abstract:
The present invention provides a power conversion device (100) with which a ripple current of a smoothing capacitor (22) can be reduced by controlling the output voltage phase of a device. This power conversion device (100) is provided with a single phase converter (21) and a single phase inverter (23), and controls the inverter (23) using: an input current phase difference (θS) with respect to a power source voltage phase (ωSt) of a power source inputted to the converter (21); an output current phase difference (θL) with respect to an output voltage phase outputted by the inverter; an output voltage phase difference reference calculating unit (61) that calculates and outputs an output voltage phase difference reference (θMF) from the power source voltage phase; and the output voltage phase difference reference (θMF).
