Abstract
A new control method to improve the performance of DC-DC converters is proposed in this paper. The proposed control method is based on a new virtual capacitance concept. Because the capacitor is not real, a large capacitance can be obtained without taking much space and cost. Moreover, a virtual capacitance can be designed to have nonlinear characteristics and respond selectively to the desired signals. By using the proposed virtual capacitance, the output voltage of DC-DC converters can be made robust against various disturbances. Simulated and experimental results are included to show the validity of the proposed concept.
