Solidstate power conversion  A Fourier analysis approach to generalized transformer synthesis
Abstract
Consideration is given to the design and Fourier analysis of a family of solidstate power converters which synthesize the assigned slowvarying waveforms by means of highfrequency switching, thereby requiring a minimum of reactive elements. The basic structure of this type of power converter is analyzed in terms of a switching matrix model of the electronic switches, and a general waveform synthesis technique is presented which makes little use of reactive elements. A general condition is presented for the applicability of this type of conversion in a given situation, and a method is proposed which allows a straightforward design of a converter if the condition is met. A general model is introduced in which the converter is represented as a twoport multipole timevarying linear circuit element consisting of a matrix of linear modulators. Finally, an example is presented of the design of an acac converter capable of sinusoidal waveform, frequency, amplitude, phase and power factor conversion, which can be regarded as a generalized transformer.
