Abstract
An apparatus and method is presented for implementing and controlling a voltage converter with one input voltage and multiple output voltages. In the case of boost and buck-boost converters, a converter circuit with one inductor and a switched group of parallel connection capacitors is realized, one parallel connection for each output voltage. A duty ratio is monitored for the inductor and the switched group of capacitors to provide a set of duty ratios. The duty ratios form a control vector which describes the control inputs. The output voltages are the control outputs describing a MIMO system. A generalized Cuk-Middlebrook modeling approach is applied to the voltage converter, along with linearization and MIMO control methods to regulate all output voltages to desired levels.
