Abstract: The AC\AC converter described in this work can be employed in microgrids. The topology which is being brought forward is used to connect a single-phase renewable energy resource to the grid. The source is coupled to a single-phase PFC boost converter, which enhances the input power factor and maintains a regulated DC output voltage utilizing two feedback loops: outer voltage loop control and inner current loop control. The single-phase stand-alone inverter receives the output of the PFC boost converter. A symmetrical sinusoidal output voltage waveform should be produced and maintained by the inverter. The transformer receives the inverter's output and offers isolation between the grid and the source. The PFC boost converter receives the transformer's output. The stand-alone inverter connected to the grid receives the output of the PFC boost converter. The pulses for the switches in the single-phase inverter coupled standalone system was generated using a sinusoidal pulse width modulation approach. Current Mode Control is modelled for varied load fluctuations to ensure proper power flow from input to output. There are two feedback loops: an outer voltage feedback loop and an inside current feedback loop. The sinusoidal PWM approach is considered for generating the switching pulses to the stand-alone inverter. The simulation results are achieved by varying the load, maintaining a constant voltage and observing whether the current varies as the load changes.
