“…Ibrahim et al [32] studies on a topology consist of four active switches, two diodes, two inductors and two capacitors. In the study of Sari and Chandrabose [33], four active switches, two inductors and one capacitor are used in the presented topology. The two studies give the detailed dynamic analyses of the proposed inverter topologies but the real parasitic effects are not considered in the calculations.…”

This study presents a new and robust single-phase inverter based on the buck-boost converter. The proposed inverter topology has minimised numbers of active and passive elements that provide less complexity and cost. Unlike similar studies in the literature, an efficient hybrid control technique is used for the control of the inverter operation. The hybrid control technique is comprised of the traditional feedback proportional-integral-derivative (PID) controller and the new proposed openloop control technique called 'control law'. This hybrid control technique provides stable and high response performance operation for the proposed inverter while the system parameters change. The proposed inverter can operate with a wide range of output frequency and output voltage value on different load conditions while satisfying <5% voltage total harmonic distortion (THD) value of the output voltage. An experimental laboratory setup with the values of 0.5 kW, 0-100 V p and 0-50 Hz is built for the proposed inverter. The experimental results demonstrate that the proposed inverter can produce high-quality output voltage with <5% THD on different input and output system parameters.
