EN In this article a simulation model of impulse matrix AC/AC converter was presented. Unfortunately these converters, despite profitable wave – form of current, have a small watt – hour efficiency. In order to improve this efficiency the algorithm of control without dead time was applied. Additionally the number of transistor switchings was reduced. In consequence the efficiency in these converters is higher.
