Small-Signal Modelling of the Three Switch 1L2C Boost Converter

The paper derives the small-signal state-space model, the continuous and discrete transfer functions for the three switch 1\mathrm{L}2\mathrm{C} boost DC-DC converter. A capacitive loop occurs in the first topological state of the converter and thus it is difficult to calculate the small-signal mode...

Summary:The paper derives the small-signal state-space model, the continuous and discrete transfer functions for the three switch 1\mathrm{L}2\mathrm{C} boost DC-DC converter. A capacitive loop occurs in the first topological state of the converter and thus it is difficult to calculate the small-signal model using usual approaches. The paper presents the analytical and simulation results together with the computations in \mathrm{MATLAB}^{\mathrm{T}\mathrm{M}} and finally the validation provided by measurements on a practical prototype.
