Popis: A method for reducing the size of filter inductance in DC-DC converter circuits based on Filippov’s theory is presented in this paper. In this method, the state transitional matrix of the system over one complete switching cycle, including the state transitional matrices across the converter switching events, is used to stabilize converter operation with a substantially reduced inductor size while maintaining circuit average currents and voltages. An analysis of circuit conduction losses shows that losses are not significantly affected by higher inductor current ripple resulting from the use of the smaller inductor. The switching frequency of the converter will not vary or change compared to a conventionally designed DC-DC converter. The new control/design method is demonstrated using an experimental voltage-mode-controlled buck converter.
