Abstract
The system includes a plurality of first converters, a second converter, an inverter, and a controller. The controller obtains a sum of input voltages of the plurality of first converters connected in series to each other; when the sum of the input voltages of the plurality of first converters is greater than a first voltage, adjusts the output voltage of the first converter, so that the sum of the input voltages of the first converters is less than or equal to the first voltage; and when the sum of the input voltages of the first converters is less than a second voltage, adjusts an output voltage of the second converter, so that the output voltage of the second converter is greater than or equal to the second voltage, and the first converters keep in a state of adjusting the input voltages based on power.
