Inverter, also known as power regulator, can be divided into independent power supply and grid-connected use according to the use of inverter in photovoltaic power generation system. According to the waveform modulation method, it can be divided into square wave inverter, step wave inverter, sine wave inverter and combined three-phase inverter. For inverters used in grid-connected systems, they can be divided into transformer-type inverters and transformer-less inverters according to whether there is a transformer. The role of photovoltaic inverters The inverter not only has the function of DC-AC conversion, but also has the function of maximizing the performance of the solar cell and the function of system fault protection.
