To design a controller for the solar power Inverter to nullifying the temperature effect

Abstract

The output waveform of sine triangle pulse width modulation at different modulation index is a crisp waveform. This waveform can be completed by adding another waveform. It is called a clamp waveform. This concept is called C to C concept or clipper clamper concept. The single-phase controller circuit is shown below. According to this circuit, anti-parallel diodes with constant DC supply connect to the grid supply. The extension of this circuit i.e. the 3-φ clamper circuit has been shown in The output of controller circuit is added up with NPC inverter.
