Title:
LOSS-BALANCED MODULATION METHOD FOR ANPC TOPOLOGY AND CONVERTER
Document Type and Number:
WIPO Patent Application WO/2024/077942
Kind Code:
A1
Abstract:
The present application provides a loss-balanced modulation method for ANPC topology and a converter. The loss-balanced modulation method for ANPC topology comprises: after determining a positive half cycle and a negative half cycle of an alternating-current (AC) side voltage of the ANPC topology, for the same half cycles, an inner tube and an outer tube of a corresponding half bridge arm in the ANPC topology alternately performing turn-off actions so as to achieve a corresponding zero-level output state. On and off times of the inner tube and the outer tube are enabled to be similar, so that switching loss of the inner tube and the outer tube can be shared, and the inner tube and the outer tube are alternately turned on and off, so that loss balance between the inner and outer tubes can be implemented.
