Brief
Description Solar energy is the
most promising energy source for the
future. Grid Interactive Solar PV Power
Plant of MW rating exports power
generated by Solar PV Array to grid.
Major components of the system are the
PV array, power converter, filter and
voltage matching transformer. The power
converter is made of IGBT switches and
its operation is controlled through
digital controller built with advanced
Digital Signal Processor (DSP). The
indigenously developed Power
Conditioning Unit (PCU) is suitable for
Indian grid conditions.
