文摘

A current sensorless MPPT is proposed for PV grid-connected VSIs. The current sensor is substituted with the sine value of the power-angle. Power-angle is the phase angle between inverter’s output voltage and grid voltage. A theoretical framework, simulation model, experimental verification are provided.
