Active Impedance Source Based Inverter with Continuous Source Current

This paper proposes a new active impedance source inverter topology. The proposed inverter provides a continuous source current, appropriate boost-factor, a few numbers of components, low voltage stress on active switch and diodes, low voltage stress across capacitors, and low volume and size. All operating modes of the proposed inverter are analyzed in details, and the design considerations of active and passive components are done. Also, a control method to generate the desired output waveform is proposed. In the following, the comprehensive comparison between the proposed topology and some conventional topologies from different points of view, such as the boost-factor, total voltages across capacitors, total blocked voltages across impedance side diodes, active switch, and volume of passive components are calculated. Ultimately, the simulation results are obtained from a prototype in the PSCAD software. The obtained results from simulation part validate the correctness of operation and performance of the proposed topology as well the given in theoretical part.
