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.
