“…As depicted in Figure 9A, the converter input current is equal to 2.06 A, which is close to theoretical value 2 A, which can be derived from (32). In this mode, as can also be seen in Figure 9, unlike either the traditional ZSI or the VSI, 24 the inverter input current that is the same as i L1 , is continuous and constant is an advantage. The maximum THD percentage for the output current is measured by a power analyzer as 1.4.…”

“…These bulky capacitors, as a filter located in the DC‐bus, will increase the inverter cost and also reduce the system speed response. In most four‐switch structures, such as those suggested in, bulky capacitors are utilized in the DC‐bus side, whereas in the proposed structure, the DC‐bus capacitors are very small. The load currents percent THD of the suggested inverter is found to be lower than those of other similar topologies as introduced in previous studies .…”

Summary This paper proposes a novel cost‐effective feature as a three‐phase four‐switch inverter utilizing a modified quasi Z‐source (MQZs) network. This inverter exploits a pulse‐width modulation (PWM) control strategy based on developed space vectors to provide balanced three‐phase output voltages and currents. It also has many applications such as the three‐phase induction motor (IM) with adjustable speed drive (ASD) fed by a DC and/or rectified AC supply. Unlike some other similar four‐switch inverters or converters, which can only work in step down (buck) mode or step up (boost) mode, this inverter can operate in both modes that depend on switching signals and due to adjusting the zero shoot‐through (Zsh‐th) duty cycle. It also decreases the total harmonic distortions (THD) of output voltages and currents. The MQZs inverter reduces the switching losses and the cost of topology in comparison with the conventional six‐switch topologies. The utilized control strategy can work well without any extra filtering circuit in DC side to eliminate the effect of the DC‐bus voltage ripples on the inverter output currents and voltages. The experimental results are found closely analogous and confirm the aforementioned features of the proposed topology compared with other traditional topologies, although the inverter output filter is a conventional LC filter.

This paper proposes a transformation matrix to generate two phase reference voltage signals for Four Switch Three Phase Inverter (FSTPI) using vector control. The feasibility of the control strategy is verified by proving the power invariance before and after the transformation. Simulation and experimental results have verified the validity and effectiveness of the proposed method to obtain instantaneous response in different operating conditions and provide fast speed response.

The converter consisting of a single-phase half-bridge rectifier and four-switch three-phase inverter is a low-cost power converter with complicated operating constraints. It is difficult to control by the conventional strategies. This study proposes a hybrid predictive control strategy with dual loops for this converter. In the outer loop, a proportional-integral controller is designed to regulate the dc-link voltage, capacitor voltage balancing, and the speed and flux of induction motors (IM). Also, in the inner loop, the finite set model predictive control is employed to control the ac input current and stator currents of the IM. The major advantages of the control strategy include: (i) easy to deal with complicated constraints and manage multiple control targets; (ii) without the need of modulators; (iii) good dynamic response. The simulation and experimental results indicate that the proposed method can guarantee the stable operation and good performance.
