Generation, Classification and Analysis of Switched-Mode DC-to-DC Converters by the Use of Converter Cells

A method is presented which combines generation, classification and analysis of DC-to-DC PWM converters. Fundamental blocks known as converter cells can be used to generate a plethora of converters leading to a number of useful new converter topologies. A classification of basic converters is proposed in terms of converter-cell generated families. The converter cells considered may be seen as three-terminal devices for which terminal characteristics may be easily found. DC and AC small-signal models for each converter cell can be derived obviating the need to rederive these models for each of the converters of a particular family.
