Robust control design for a conventional series resonant converter using /spl mu/-synthesis

摘要: Because of their reduced switching losses, DC-to-DC resonant converters have been used extensively in the design smaller size and lighter weight power supplies. The steady state dynamic behaviors both conventional series parallel thoroughly analyzed small-signal models around given nominal operating points obtained. These past to controllers that attempted keep output voltage constant presence input perturbations. However, these did not take into account neither load nor components variations, this could lead instability face component or changes. Moreover, prediction frequency range for stability was done a posteriori, either experimentally by trial error approach. In paper we use /spl mu/-synthesis robust controller converter. addition objectives include rejection disturbances at converter while keeping control settling time within values compatible with practical implementation. >
