Current-free synthesis of parameter-free zero-impedance converter (an ideal adaptive and self-tuning control algorithm)

A current-free synthesis of a parameter-free zero-impedance converter is presented. The converter is used in synthesizing load-independent switch-mode power converters and electric motor drive systems of infinite disturbance rejection ratio and zero-order dynamics with adaptive/self-tuning control properties. The current-free and differentiation-free operation implies freedom from noise and ripple generated in switched circuits. Both computer simulation and experimental results confirm the theory and show the advantages of the proposed control method
