Abstract :
The application of H∞ theory to DC-to-DC switching converters is investigated in this paper. Using an averaged linear model of the converter, a robust controller is developed, this guaranteeing stability and the desired closed-loop dynamic response. Boost and buck-boost converters illustrate the application of the control method
