Abstract

The paper is concerned with the design of the bang-bang control for dual channel DC-DC buck and boost converter. The quality of the control is characterized by two quality figures, the voltage ripple and the voltage error. An optimum design method is described to realize good quality figures. When the output voltage is higher (lower) than the reference voltage the lower (higher) switching frequency is selected. In order to reduce the output voltage ripple the lower switching frequency is changed with the variation of the load. Calculation and simulation results of the two quality figures are presented and compared.
