In this paper, a novel single-stage single-phase buck–boost inverter is presented. The proposed inverter uses only four power electronic switches. The four switches can be IGBTs or two of them can be replaced by two thyristors which allows an inherently simple and compact design.
However, a buck–boost operation is achieved, the single-phase inverter needs two isolated DC sources and the three-phase one needs six. This represents a limitation, as these converters cannot be supplied from only a single source. In this paper, a novel single-stage single-phase buck–boost inverter is presented.
Conclusion A buck–boost converter and a full-bridge inverter are combined to generate the single-stage inverter that is provided. The dynamic timing of response and voltage accuracy is improved by using feedforward control and PWM.
The output voltage from this inverter is always lower than the DC input one. In other words, it provides bucking for the input voltage. To achieve a boosting feature from this inverter, a boost-type DC–DC converter is used with the conventional buck inverter topology, as shown in Fig. 1 b.
