PHOTOVOLTAIC POWER GENERATION SYSTEM - A simplified explanation of the abstract

This abstract first appeared for US patent application 18520763 titled 'PHOTOVOLTAIC POWER GENERATION SYSTEM

Simplified Explanation

The patent application describes a photovoltaic power generation system that includes a single-stage inverter, an anti-backflow circuit, a photovoltaic string, and a coupling capacitor. The system is designed to prevent backflow current from flowing back to the photovoltaic string.

• The system includes a single-stage inverter, an anti-backflow circuit, a photovoltaic string, and a coupling capacitor.
• The anti-backflow circuit is connected to one input end of the single-stage inverter.
• One output end of the photovoltaic string is connected to the other input end of the single-stage inverter.
• The other output end of the photovoltaic string is connected to the anti-backflow circuit.
• The photovoltaic string includes a buck optimizer and a photovoltaic panel.
• The anti-backflow circuit is configured to prevent backflow current from flowing back to the photovoltaic string.
• The coupling capacitor is connected in parallel to two ends of the anti-backflow circuit and is configured to transmit a signal between each buck optimizer in the photovoltaic string and the single-stage inverter, to control backflow of the backflow current when the anti-backflow circuit fails.
