Abstract
The paper presents a control system for a quasi-Z-type inverter connected to an AC power grid. The control system was implemented with the MicroLabBox development system, which was used for the first time to implement such a control system. The basic operating principle of the quasi-Z-type inverter and the inverter control system are presented. The MicroLabBox embedded computer system is described and its architecture is given. The simulation of the observed inverter was made as a co-simulation of the MATLAB-Simulink and Simplorer programs. A laboratory model was implemented and a comparison of experimental and simulation results is given.
