Control of Series Resonant Converter with Robust Performance Against Load and Power Circuit Components Uncertainties

Robust performance controller design for duty-cycle controlled series resonant converter (src) is proposed in this paper. the uncertainties of the converter are analyzed with load variation and power circuit components tolerances are taken into consideration. additionally, a nominal performance (np) controller is designed. closed-loop system is simulated with orcad and simulation results of robust controller are compared with nominal performance controller. although nominal performance controller has better performance for nominal plant, the robust performance controller is advantageous in dealing with uncertainties.
