Abstract
This paper proposes a novel topology of a power flyback inverter, which is intended to be used in a microgrid system, as an interface between a low DC voltage line bus and a part of 230 V AC loads. In addition to galvanic isolation, this topology offers other advantages like high conversion ratio and a low number of power switches. Moreover, only two of the four transistors operate at high frequency, the other two switching at AC line frequency. Only one driving signal is needed for the high-frequency transistors, because they are in opposite phase and this leads to a simpler control implementation. A simulation model was realized using parameter values obtained after a basic design procedure for all the components. The inverter model was tested through digital simulation using a PI control, verifying its stability and obtaining values for the voltages and currents through the circuit.
