Abstract
A new method for an input current waveform correction in typical power converters is described. It assumes an implementation of the so-called virtual transformer with a fast-changing voltage ratio. Theory and calculations are presented to confirm the method validity. Practical implementation is left out of the scope of the given paper due to size limitations.
