Computer-aided analysis of electronic DC-DC transformers

An approach to the analysis of electronic DC-to-DC transformers using the SPICE simulation program as an aid is presented. In this approach, the minimum separable switching configuration (MISSCO) of a DC-to-DC transformer is first identified and its equivalent circuit determined before analysis and simulation are carried out on the complete converter circuit. Both the modeling of the MISSCO and the simulation using SPICE program can be easily performed to produce plots of frequency and phase characteristics of the circuit, which are useful for design purposes. A full analysis of the DC-to-DC transformer is also described to enhance an understanding of the circuit behavior, in addition to just modeling and simulation.<
