This book is the study of abyss of stability and unstability, for different coefficients in the transfer function of compensators designed for known buck-boost converter. The 234 colored Bode plots of the compensators - P, I, PID, series PI, parallel PI, One pole one zero (1P1Z), multipoles, two pole two zero (2P2Z) and three pole three zero (3P3Z) are given with the explaination in brief of the known theory.
Very interesting exhaustive results are fully tabulated like (i) due to one variable change, which other variables change or do not change and how it affects phase margin, gain margin and stability, at the same frequency (ii)How same coefficients behave at different frequencies.
Due to colored print-out of graphs, the book is costly but it can be freely downloaded from author’s IEEE preprint webpage (by Google search).
