Abstract

This paper gives a new classification of soft-switching inverters according to the principle of operation. After discussing the soft-switching phenomena in hard-switching inverters, the concept of soft-switching vector (SSV) is introduced. The proposed SSV is not only helpful in analyzing the changes of switching states, but also easily realized in control scheme. Theoretical analyses are conducted step by step for both with and without SSV control applied to resonant snubber based inverters (RSI). The experimental results closely agree with theoretical analyses and show the significant reduction in power loss after using SSV. Moreover, a modified version of SSV is also presented to achieve the better working condition at low load current with current ripple.
