Differential-mode inverter topologies are promising for renewable energy generation since they offer advantages such as passive elements sizes reduction, having decreased power losses and reduced total cost. Single phase buck–boost differential-mode current-source inverters (DMCSIs) can deliver wider range of output voltage above or below the input dc voltage, which is necessary for high-efficiency...
Higher level of inversion is achieved with a less number of switches in the proposed scheme. The scheme proposes a five-level inverter for an open-end winding induction motor which uses only two DC-link rectifiers of voltage rating of Vdc/4, a neutral-point clamped (NPC) three-level inverter and a two-level inverter. Even though the two-level inverter is connected to the high-voltage side, it is always...
This paper describes a novel control strategy of an instantaneous power based CVCF inverter. The most important feature of this strategy is a direct selection of switching states of the CVCF inverter to restrict errors between feedback values and command values of the active and reactive power. A theoretical analysis on relationship between the instantaneous power and the switching states is investigated,...
