Title:
POWER CONVERSION DEVICE AND CONSTANT ACQUIRING METHOD
Document Type and Number:
WIPO Patent Application WO/2019/207640
Kind Code:
A1
Abstract:
A positive-side arm of a power converter has a plurality of converters connected in series with each other and a first end connected to a positive-side DC terminal. A negative-side arm of the power converter has a plurality of converters connected in series with each other and a first end connected to a negative-side DC terminal. The power converter is provided with a four-winding transformer including: a third winding having a polarity opposite to that of a secondary winding and magnetically coupled to a primary winding; and a fourth winding connected in a delta configuration. A converter control device controls the switching elements of the arms to output a voltage for cancelling disturbance voltages induced in the secondary and third windings due to the fourth winding.
