4. Overall Introduction
4.1 Circuit Structure
Figure 2 shows main circuit of KSG-10K/12K/15K/17K/20K 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.
