Description
Summary:A zeta converter is a fourth-order DC-DC converter made up of two inductors and two capacitors and capable of operating in either step-up or step-down mode. Compared with a Cuk or Sepic converters, the zeta converter has received the least attention and its dynamic properties have never been reported before in the literature. This paper presents dynamic modeling of a zeta converter with state-space averaging (SSA) technique. The modeling leads to a small-signal linear dynamic model of the converter, from which the transfer functions used for feedback control design can be determined. Simulation results are presented to verify the accuracy of the obtained model.
