4. Overall Introduction
4.1 Circuit Structure
Figure 2 shows main circuit of KSG-12K inverter by which the direct
current is input via three-phase full-bridge circuit and transformed into
sine-wave current through filter and output to power grid. To make the
photovoltaic array generate in maximum power, the new type power
devices are adopted for this machine and the advanced MPPT
algorithm is used at the DC side.
