Parallel operation of voltage source inverters
IEEE Transactions on Industry Applications, 1988 Parallel operating systems of voltage source inverters with other inverters or with the utility source are sensitive to disturbances from the load or other sources and can easily be damaged by overcurrent. Thus extremely careful attention should be given to the system design of parallel operating inverters.

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-
