In this paper a new 5-level single phase symmetrical cascade multi-level inverter is proposed. The proposed topology contains combination of unidirectional and bidirectional power switches based on output voltage level number. The number of power switches and withstanding voltage of powers witches were reduced related to the other topologies. This configuration can be extended to the n-level in...

We consider an original ternary number system called the ternary mirror-symmetrical number system in the article. It is a synthesis of the classical ternary symmetrical number system and the number system with an irrational base called Bergman’s number system. The main engineering result is a development of an original matrix and pipeline ternary mirror-symmetrical adder, which can be used for ...
