摘要:
A solar drive system, having: at least one photovoltaic array generating a DC current; at least one inverter electrically connected to the photovoltaic array for inverting the DC current into an AC current; at least one electric motor electrically connected to the inverter for supplying the electric motor with the AC current; and at least one device for determining a present rotational frequency of the electric motor; wherein the inverter is configured to track a maximum power point of the photovoltaic array by performing a Perturb and Observe Maximum Power Point Tracking method and to determine a step direction of the Perturb and Observe Maximum Power Point Tracking method using the determined present rotational frequency of the electric motor.
