Inverter

Description

The inverter, also known as power regulator, can be divided into two types (one for independent power supply and the other for grid connection) as per its purpose in PV power generation system, and can be distributed into square-wave, step-wave, sine-wave and combined three-phase inverters as per the modulation system of waveform. For the inverter used in the grid-connected system, it can be divided into transformer-type inverter and transformer-free one as per whether there is a transformer.
