A novel dual switch quadratic Zeta architecture
with a broad conversion ratio and non-inverting output voltage
features is present in this paper. It has broader bucking
characteristics in comparison to the Zeta converter and provides
a continuous source current. The theoretical circuit analysis
and subsequent simulation will verify the features. The transfer
function is realized via state-space modeling, and pole-zero plots
are compared with the traditional Zeta converter topology to
elaborate on its stability. PI controller is designed to improve the
stability of the circuit by increasing the gain/phase margin and
response speed of the sixth-order system.
