Abstract :
Three techniques are employed to derive small-signal models for the series-parallel resonant power converter over a range of operating conditions which includes the discontinuous capacitor voltage mode. A comparison of the results with experimental data is undertaken to quantify the limitations and accuracy of each technique. The three techniques are: sampled-data; extended describing function; and an approximate method
