Virtual Oscillator Control of Equivalent Voltage-Sourced and Current-Controlled Power Converters
Energies, 2019 The dynamics of a general class of weakly nonlinear oscillators can be used to control power converters to create a self-forming AC network of distributed generators. Many control stability results for these “virtual” oscillators consider the

Stability of interacting grid-connected power converters
Journal of Modern Power Systems and Clean Energy, 2013 The power grid in a typical micro distribution system is non-ideal, presenting itself as a voltage source with significant impedance. Thus, grid-connected converters interact with each other via the non-ideal grid.

Quasi Z‐source inverter with switched‐capacitor‐inductor for enhancing boost factor
IET Power Electronics, 2021 Two structures are proposed based on the quasi Z‐source inverter (qZSI), which can significantly raise the output voltage in applications, including photovoltaic and fuel cells, in which the input voltage is low.

A Single-Phase Embedded Z-Source DC-AC Inverter
The Scientific World Journal, 2014 In the conventional DC-AC inverter consisting of two DC-DC converters with unipolar output capacitors, the output capacitor voltages of the DC-DC converters must be higher than the DC input voltage. To overcome this weakness, this paper proposes a single-
