Design and Implementation of a DSP Based Dual-Loop Capacitor Voltage Control of the Z-Source Inverter Vrije Universiteit Brussel
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 Digital Signal Processor (DSP) ...
