The Z-source inverter is a recently proposed single stage converter topology with buck-boost capabilities. This paper proposes a dual-loop capacitor voltage control, with outer voltage loop and inner current loop, of the Z-source inverter (ZSI). Both controller are designed based on a third order small signal model of the ZSI using the direct digital design method. Real-time control algorithm is implemented using DSP linked with MATLAB real time workshop (RTW) as rapid prototyping tool. The feasibility of the proposed dual loop control method has been verified by the simulation and experimental results.
