Solar plants based on single-stage conversion photovoltaic (PV) inverters (no dc-dc boost stage) have gained popularity due to their simplicity, high efficiency, and cost effectiveness. Existing PV plants mostly operate under 1000 V and are subject to wide dc-bus voltage variations due to the effect...
