Designing impedance network of Z-source inverters
2005 International Power Engineering Conference, 2005The possible operating states of an impedance network of a Z-source inverter are identified and analyzed with the objective of deriving design guidelines. Through the analysis it is shown that in addition to the desired three dynamic states, the operating cycle can contain another three static states that do not contribute to the power conversion ...
