Abstract

© 2015 IEEE. This paper presents the dynamic modeling of a two-input Zeta converter topology using State-space averaging (SSA) technique. The modeling leads to a small-signal linear dynamic model of the multiple-input converter (MIC), from which the transfer functions used for feedback control design can be determined. To verify the accuracy of the obtained model, a two-input Zeta converter with inputs from PV array and wind turbine generation system (WTGS) is designed which can produce an output voltage of 350 Vdc and an output power of 1kW. A controller for this is designed based from the transfer functions derived from the dynamic analysis conducted. Simulation tests of the design are performed using blocks and component of Matlab/Simulink from its SimPower Systems Toolbox. Results are presented to verify the accuracy of the obtained model.
