This paper presents a developed impedance-type power inverter that is termed switched-inductor Z-source inverter. To enlarge voltage adjustable ability, the proposed inverter employs a unique switched-inductor impedance network to couple the main circuit and power source. Compared with the classical Z-source inverter, the proposed inverter increases the voltage boost inversion ability significantly,...
In this paper, control of parallel single-phase inverters in direct-quadrature(DQ) rotating frame based on droop method is proposed. For each inverter, a secondary orthogonal imaginary circuit is created to provide the second phase required for the transformation; thus a DQ model of the inverter is obtained. The DQ transformation provides a time-invariant model of the inverter which makes the control...
This paper establishes the criteria to ensure stable operation of two-stage, bidirectional, isolated AC-DC converters. The bi-directional converter is analyzed in the context of a building block module (BBM) that enables a fully modular architecture for universal power flow conversion applications (AC-DC, DC-AC and DC-DC). The BBM consists of independently controlled AC-DC and isolated DC-DC converters...
This project proposes an impedance-source inverter and its control method for implementing dc-to-ac, ac-to-dc, ac-to-ac, and dc-to-dc power conversion. The Z-source converter employs a unique impedance network to couple the converter main circuit to the power source. The Z-source converter overcomes the conceptual and theoretical barriers and limitations of the traditional voltage-source converter...
