Is the PV inverter a current source or a voltage source?
Inverter is a kind of semiconductor device composed of power adjustment device, mainly used for DC power into AC power.
Photovoltaic inverter, also known as power regulator, according to the inverter in the use of photovoltaic power generation system can be divided into two kinds of independent power supply and grid.
The inverter is mainly composed of a switching element such as a transistor, and turns the DC input into an AC output by repeatedly turning ON-OFF the switching element in a regular manner.
According to the waveform modulation method can be divided into square wave inverter, stepped wave inverter, sine wave inverter and modular three-phase inverter.
For the inverter for the grid system, depending on whether the transformer can be divided into transformer-type inverter and transformer-free inverter.
