Synthesis of zero-admittance converter

摘要

A method of synthesizing a power conversion system which converts a finite value of an admittance to zero, with associated finite voltage and zero current, is presented. The synthesis method comprises a positive voltage feedback within a negative current feedback. The positive feedback loop incorporates a block of exactly specified nature and value of its transfer function providing for the zero-admittance algorithm. The negative feedback loop controls stability and dynamics of the system. A particular derivation of the zero-admittance power converter is applied in synthesizing a load-independent constant-current switch-mode power converter.
