The working principle of a solar inverter can be summarized in the following steps:
1. The DC power generated by the solar panel passes through an input filter to remove impurities before entering the inverter bridge.
2. In the inverter bridge, the DC power is converted to AC power by controlling the on and off switching of the switches. This process requires precise control to ensure that the output AC power meets grid standards.
3. The converted AC power passes through an output filter to remove high-frequency components before being output to the grid or power supply.
4. Throughout this process, the control circuit continuously monitors and controls the inverter's operating status to ensure safe and stable operation.
