TLDR
In this paper, a dc-ac converter with a magnetic circuit has been proposed, which can be converted to alternating sine wave voltage with an optional frequency and even if the load current is increased, the values of the output voltage and its frequency are constant over a wide range.Abstract:
The following is a brief description of the operation principle and the circuit configuration of a new dc-ac converter proposed by the authors. This device is constructed by a magnetic circuit of unusual shape and has a number of excellent characteristics in the operation. Therefore dc voltage can be converted to alternating sine wave voltage with an optional frequency, and even if the load current is increased, the values of the output voltage and its frequency are constant over a wide range.read more
