Title:
DIRECT CURRENT VOLTAGE CONVERSION DEVICE AND BRIDGE ARM CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2016/029824
Kind Code:
A1
Abstract:
A direct current voltage conversion device and a bridge arm control method therefor. The device is a structure having a single phase, two phases or more than two phases, each phase consisting of a basic function module, the basic function module comprising device cascade structures (S1, S4) connected in series and a sub-module cascade structure. Via combination of the device series connection structures and the sub-module cascade structure, voltage conversion may be implemented without a transformer, soft switching of series connection devices may be implemented, and investment and space may be reduced.
