A new approach to real approximation of an ideal sinusoidal frequency conversion process is put forward in the present report. This enables the output frequency range of line-commutated direct frequency converters to be expanded up to the value of input frequency. This is achieved by the application of a low frequency value sinusoidal modulating function and the replacement of input voltage and modulating function product with approaching input voltage level intervals. An example of this frequency conversion in terms of the simplest six thyristor circuits is considered for a fan drive.
