Title:
POWER CONVERSION APPARATUS, POWER CONVERSION SYSTEM, AND METHOD FOR CONTROLLING POWER CONVERSION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2019/159467
Kind Code:
A1
Abstract:
According to the present invention, a power conversion apparatus is achieved which can suppress a pulsation component changing at a primary-side or secondary-side frequency, and can be configured in a small size and at low cost. In this power conversion apparatus, power conversion cells are connected such that electric power can be supplied from phase 1 of a 3-phase AC system connected to primary sides of the power conversion cells to phase 3 of a 3-phase AC system connected to secondary sides of the power conversion cells. Primary-side power and secondary-side power of each of the power conversion cells are controlled to include a phase power component of the phase connected to the primary sides and a phase power component of the phase connected to the secondary sides. Accordingly, a pulsation component which changes at a primary-side or secondary-side frequency is suppressed.
