The power inverter module is also called a power conditioner. According to the use of the inverter in the photovoltaic power generation system, it can be divided into two types: independent power supply and grid connection. According to the waveform modulation method, it can be further divided into a square wave inverter, a staircase wave inverter, a sine wave inverter and a combined three-phase inverter. For the inverter used in the grid-connected system, it can be divided into a transformer type inverter and a transformerless type inverter according to the presence or absence of a transformer. Generally, the process of converting AC power into DC power is called rectification, the circuit that completes the rectification function is called a rectification circuit, and the device that implements the rectification process is called a rectification device or a rectifier. Correspondingly, the process of converting DC power into AC power is called inverter, and the circuit that completes the inverter function is called an inverter circuit, and the device that implements the inverter process is called an inverter device or an inverter.
