Abstract
A new concept of soft-switching vector (SSV) is proposed for soft-switching inverters, especially those resonant snubber inverters (RSIs). The SSV control approach is not only useful for achieving the soft-switching condition, but also provides some definite advantages namely the reduction in power loss and the elimination of over-current problem in the main switches. In this paper, softswitching inverters are firstly classified by their operating principles. Then, the operating modes of a RSI with and without using SSV control are presented. Both simulation and experimental results verify the theoretical analysis, showing that the use of SSV control can provide the above advantages.
