Abstract

Cascaded H-bridge inverters with separated DC sources charging the DC-link are widely used in the industry application due to its inherent advantages. However, a failure of the DC sources can interrupt the power supply which results in economic loss. This paper proposes a soft-switching modulation algorithm to tackle this issue. A pre-set table lists all of the possible redundant module states that can adjust the voltage of the DC-link. With this method, the DC voltages can be always balanced even under DC source failures, resulting in good flexibility, good dynamic performance and no voltage level-skip. Hence, a reliable and continuous power supply is guaranteed. Finally, 3-module experimental results verify the validity of the proposed method and simulation tests are used to verify its balance limitations.
