“…The switch-mode inverter topologies are developed through the reorganizing of the direct current-direct current (DC-DC) converters to be able to produce alternative voltages. Although buck-, [14][15][16] boost-, [17][18][19][20] buck-boost-, [21][22][23][24] and Cuk-type [25][26][27] switch-mode singlephase inverters in quite numbers are successfully developed, the limited numbers of three-phase switch mode inverters find place in the literature with such as buck, 28,29 boost, 30,31 and Cuk 32,33 types. Buck-boost-type switch-mode three-phase inverters are also studied in the literature, and a comparative brief analysis of these studies is given in the below paragraph.…”

Summary A novel general purpose three‐phase buck‐boost inverter without need of additional filtering units is presented in this study. The proposed inverter topology is built with moderate numbers of elements in terms of the operation advantages and qualities. The buck‐boost converter‐based structure provides obtaining wide‐range output voltage amplitudes lower or higher than the input voltages. A novel hybrid control method that is open‐loop assisted closed‐loop control is proposed for the inverter operation to improve the response performance on various input and output operation conditions. The wye‐connected modular structure of the proposed inverter topology also enables unbalanced three‐phase operation and single‐phase operation for each phase with independent phase voltages and frequencies. An experimental laboratory setup is built for the proposed three‐phase inverter for 0–50 Hz, 0–100 Vp, and 1.5 kW operation values for real‐time application tests. Simulation tests are also applied for the inverter. The obtained results for both the simulation and the experimental tests show that the presented inverter with the proposed hybrid control method is capable of operating in balanced/unbalanced three‐phase and independent single‐phase modes while producing close to sine wave output voltages under 5% THD levels with wide range desired amplitudes and frequencies on different operating points.

“…Proportional–integral (PI) controller is applied for the feedback control of the inverter but the detailed controller design analyses are not given. Ho and Siu [30] proposed a topology with six active switches, two inductors and one capacitor and Krishnapriya et al [31] presents an inverter including six active switches, six diodes, one inductor and one capacitor. In these two studies, the real parasitic components are ignored in the topologies.…”

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.
